Facebook Ads for Window Companies: The Complete Guide

If you run a window company in the UK, you already know how hard it is to get a steady flow of good leads. You have probably tried leaflets, local directories, maybe even paid for shared leads from comparison sites - only to find yourself competing with four other installers for every enquiry.

Here is the thing: the homeowners who need new windows and doors are not searching Google every day. Most of them are not actively looking at all. They are sitting on their sofa scrolling through Facebook and Instagram, looking at photos of their friend's new kitchen extension and thinking, "Our windows are looking a bit tired, aren't they?"

That is exactly where Facebook ads come in. They let you put your work - your best installations, your happiest customers, your showroom - right in front of the homeowners most likely to buy, in the exact areas you serve. No competing with comparison sites. No shared leads. Just your company, your brand, your enquiries.

We have run Facebook and Instagram ad campaigns for home improvement companies across the UK, and window and door businesses are some of the best performers we see. In this guide, we are going to walk you through everything you need to know - from how much to spend, to what kind of ads actually work, to the mistakes that waste your budget.

Why Facebook ads work for window companies

There are two big reasons window companies do well with Facebook ads, and they are both fairly obvious once you think about them.

Windows are a visual product

Facebook and Instagram are visual platforms. People scroll through photos and videos all day. And windows - especially when you show a beautiful before-and-after transformation, or a stunning set of bi-folds opening onto a garden - stop people mid-scroll. Unlike something invisible like cavity wall insulation or a new boiler, windows are something homeowners can immediately see the difference of. That makes your ads more engaging, more clickable, and ultimately more effective.

You can reach homeowners before they start comparing

With Google ads or comparison sites, you are catching people who are already shopping around. They have probably requested quotes from three or four companies. You are one of many.

With Facebook ads, you reach homeowners before they get to that stage. Maybe they have been thinking about replacing their windows for months but have not got around to doing anything about it. Your ad lands in their feed at exactly the right moment - and because you are the one who prompted them to take action, you are often the only company they contact.

That means less competition on every lead, higher conversion rates, and a much better chance of winning the job at a fair price rather than being dragged into a race to the bottom.

The targeting is incredibly precise

Facebook knows an enormous amount about its users. It knows their age, where they live, whether they own their home, what they are interested in, and what they have been browsing online. For a window company that serves specific postcodes, this is gold. You can show your ads exclusively to homeowners aged 30 to 65 within a 20-mile radius of your showroom - and exclude renters who are never going to buy replacement windows. No other advertising channel gives you that level of control.

What budget do you actually need?

This is usually the first question we get asked, so let us be straightforward about it.

We recommend a minimum ad spend of £1,500 per month. That is the amount you pay directly to Facebook to run your ads - it is separate from any management fee you pay to an agency.

At £1,500 per month, a well-run campaign should generate somewhere between 40 and 60 leads, depending on your area, the products you offer, and how strong your creative is. That works out to roughly £25 to £40 per lead.

Now, think about the maths from your side. If your average window or door installation is worth £3,000 to £5,000, and you convert even one in five of those leads into a paying customer, that is eight to twelve new customers per month. At an average order value of £4,000, that is £32,000 to £48,000 in revenue from a £1,500 ad spend.

Why going too low backfires

Facebook's algorithm needs data to learn. It needs to show your ad to enough people, get enough clicks, and collect enough leads to figure out who your ideal customer is. If your budget is too small - say £300 per month - you are not giving the algorithm enough to work with. Your cost per lead stays high, your results are inconsistent, and you end up thinking "Facebook ads don't work" when the real problem was the budget was too thin.

Think of it like this: you would not open a showroom, put one small sign in the window, and expect a queue of customers. You need to give the campaign enough fuel to actually do its job.

On top of the ad spend

The ad spend goes directly to Facebook. On top of that, you will either manage the campaigns yourself (which takes time and know-how) or pay an agency to do it. Our plans start from £500 per month for campaign management, creative production, and ongoing optimisation - which is a fraction of what traditional agencies charge.

How to target the right homeowners

Getting your targeting right is probably the single biggest factor in whether your campaign succeeds or wastes money. Here is how we approach it for window companies.

Location

Start with the areas you actually serve. If you are based in Bristol and will travel up to 30 miles for an installation, set your radius accordingly. There is no point paying to show ads to someone in Newcastle if you are never going to quote for them.

You can also target specific postcodes or towns, which is useful if you want to focus on areas where you know the housing stock is older and more likely to need replacement windows - think 1930s semis, 1960s estates, or Victorian terraces with single-glazed sash windows.

Age and homeownership

Most window replacements are bought by homeowners aged 35 to 65. Younger than that and they are often renting or have only just bought their first home and are focused on other priorities. Older than 65 and they can still be excellent customers, but the volume drops off.

Facebook lets you target people who are likely to be homeowners based on their behaviour and data. This is crucial - there is no point showing your ads to renters who could not replace their windows even if they wanted to.

Interests and behaviours

You can layer on interest-based targeting to narrow your audience further. Good interests to include for window companies:

• Home improvement - people who follow DIY pages, home renovation accounts, or interact with home improvement content
• Interior design and home decor - homeowners who care about how their home looks
• Property value - people interested in Rightmove, Zoopla, or property investment (they care about increasing their home's value)
• Energy efficiency - with rising energy bills, this is a strong hook for double or triple glazing
• Specific brands - people who have shown interest in Anglian Home Improvements, Everest, or Safestyle (they are already window-shopping, if you will pardon the pun)

Lookalike audiences - your secret weapon

Once your campaign has generated its first 30 to 50 leads, you can create what is called a lookalike audience. This is where Facebook takes the data from the people who have already enquired with you and finds other people who look just like them - same age range, same areas, same behaviours, same income bracket.

Lookalike audiences are consistently the best-performing targeting option we see for window companies. They take the guesswork out of targeting because you are letting the algorithm use real data from your actual customers, rather than you guessing who might be interested.

Retargeting - do not forget about it

Not everyone who sees your ad will enquire straight away. Many people will click through, have a look, and then get distracted by something else. Retargeting lets you show follow-up ads to people who have already visited your website or engaged with your previous ads.

These retargeting ads are typically much cheaper to run and convert at a higher rate because the person already knows who you are. A simple ad saying "Still thinking about new windows? Here is what our customers say..." with a few reviews can be incredibly effective.

Ad creative that sells windows

Your targeting gets the ad in front of the right person. But it is the creative - the image or video and the text - that makes them stop scrolling and actually enquire. Here is what works.

Before-and-after photos

This is the single most effective format we see for window companies. A side-by-side showing the old, tired windows next to the finished installation is simple, visual, and instantly communicates the transformation. It does not need to be professionally shot - a decent phone photo taken on site works brilliantly, and often outperforms polished studio imagery because it feels more real.

Tips for good before-and-after photos:

• Shoot from the same angle for both photos
• Include the full window and some of the surrounding wall so people can see the context
• Take the "after" photo when the installation is clean and finished - no scaffolding, no dust sheets
• Natural daylight always looks better than flash

Video walkthroughs

A 15 to 30-second video walking through a completed installation performs extremely well, especially on Instagram Reels. The installer or business owner simply walks up to the property, shows the new windows or doors, maybe opens and closes a bi-fold, and talks briefly about what was done. It does not need to be scripted or fancy - in fact, the less polished it is, the better it tends to perform.

Lifestyle imagery

Photos that show the windows as part of a beautiful home - light flooding through new bi-folds into a kitchen, a cosy living room with sleek casement windows - work well because they help homeowners imagine the result in their own home. These are particularly effective for premium products like aluminium windows, bi-fold doors, or roof lanterns.

Social proof

Ads that feature a genuine customer quote or review tend to build trust quickly. Something like: "We had all our windows replaced by [your company name] last month. The difference to the house is incredible and we have already noticed a drop in our energy bills. Highly recommend." - paired with a photo of the actual installation - is very persuasive.

What does not work

Stock photos of generic windows. Clip-art style graphics. Long paragraphs of text in the ad. Anything that looks like a corporate brochure from 2005. Homeowners scroll past these instantly because they look like every other ad in their feed. The whole point is to stand out - and real photos of real work, from real local installations, always win.

Lead forms vs landing pages - which converts better?

When someone clicks your ad, they need somewhere to go. You have two main options: a Facebook lead form (which stays inside Facebook) or a landing page on your website. Each has pros and cons.

Facebook lead forms

Pros:

• Load instantly - no waiting for a website to load on a slow mobile connection
• Auto-fill the person's name, email, and phone number from their Facebook profile
• Higher volume of leads because the barrier to completing the form is much lower
• Easy to set up - no website changes needed

Cons:

• Lead quality can be slightly lower because it is so easy to submit (some people do it almost by accident)
• The person has not visited your website, so they know less about you

Landing pages

Pros:

• Leads tend to be higher quality because the person has taken more steps to enquire
• You can show more information about your company, products, and reviews before they fill in the form
• The person has visited your website, which means retargeting is easier

Cons:

• Lower conversion rate - every extra click loses people
• Your website needs to be mobile-friendly and fast-loading (many window company websites are not)
• Requires a dedicated landing page, not just your homepage

Our recommendation

For most window companies, start with Facebook lead forms. They generate more leads at a lower cost, and you can always add qualifying questions (like "What type of windows are you interested in?" or "When are you looking to get this done?") to filter out time-wasters.

Once you have a consistent flow of leads coming in, test a dedicated landing page alongside the lead forms and see which produces better results for your specific business. We often find that lead forms win on volume while landing pages win on quality - and the sweet spot is running both.

Common mistakes window companies make with Facebook ads

We see the same mistakes again and again when window companies try to run Facebook ads themselves or work with a generalist marketing agency. Here are the big ones to avoid.

1. Boosting posts instead of running proper campaigns

Facebook makes it very tempting to hit that "Boost Post" button. It is right there on every post you make. The problem is that boosted posts are designed to get likes and comments, not leads. When you boost a post, Facebook shows it to people who are likely to engage with it - not people who are likely to enquire about new windows. Proper ad campaigns, set up through Ads Manager with a lead generation or conversion objective, perform significantly better because the algorithm is optimising for the right outcome.

2. Targeting too broadly

Setting your targeting to "everyone in the UK aged 18-65" is a guaranteed way to waste money. You end up showing ads to students, renters, and people 200 miles away from you. Narrow your audience to homeowners in the areas you actually serve, in the age brackets that actually buy windows. A smaller, more relevant audience will always outperform a massive, untargeted one.

3. Using the wrong campaign objective

Facebook offers about a dozen different campaign objectives - brand awareness, traffic, engagement, video views, lead generation, conversions, and more. If you choose "traffic" when you actually want leads, Facebook will send lots of people to your website but optimise for clicks, not for people who are likely to fill in a form. Always choose lead generation (for lead forms) or conversions (for landing pages).

4. Not following up quickly enough

This is probably the biggest one. You can have the best ads in the world generating brilliant leads, but if you take 48 hours to call someone back, you have already lost them. Studies show that the chance of qualifying a lead drops by 80% after the first five minutes. The window companies that do best with Facebook ads are the ones that call or text every lead within minutes, not hours.

Set up notifications so you know the moment a lead comes in. Have a process for who calls them and what they say. This is not glamorous work, but it is where the money is made.

5. Giving up too soon

We see companies try Facebook ads for two weeks, get eight leads, close none of them, and decide "Facebook ads don't work." Two weeks is not enough time. The algorithm needs 30 days to properly optimise. Your first batch of leads will always be the weakest as the system learns who responds best. Give it at least 90 days before making a judgement - and make sure you are tracking which leads convert into actual jobs, not just counting enquiry numbers.

6. Running the same creative for months

Ads get stale. The same people see the same image repeatedly and start ignoring it - this is called "ad fatigue" and it shows up as a rising cost per lead. You should be refreshing your creative at least every three to four weeks with new photos, new angles, and new copy. This is one of the reasons working with a specialist agency can make a real difference - we produce new creative every month as part of the service, so your campaigns always stay fresh.

Real results from UK campaigns

Theory is one thing, but you probably want to know what actually happens when a home improvement company runs Facebook ads properly.

One recent campaign we ran for a home improvement company in Kent generated 187 leads in 90 days at a cost of £33 per lead. The client reported converting those leads into enough installations to produce a x13 return on their total ad spend. That means for every £1 they invested in advertising, they got £13 back in revenue.

You can see more details on this and other campaigns on our results page.

What made this campaign work was not some secret formula. It was the basics, done well:

• Strong creative - real photos from real installations, refreshed every few weeks
• Tight targeting - homeowners in specific Kent postcodes, aged 30 to 60
• Fast follow-up - the client called every lead within 15 minutes
• Consistent budget - they committed to a proper monthly spend and let the algorithm optimise over time
• AI-powered optimisation - we use artificial intelligence tools to test and improve ad creative faster than any human team could

That last point is worth expanding on. Traditional agencies have a creative team that produces a handful of ad variations and then tests them manually over weeks. We use AI to generate and test dozens of creative variations, analyse what is working in near real-time, and feed that data back into the next round of creative. It means your campaigns improve faster and your cost per lead comes down sooner.

What does this look like month by month?

The key message here: this is not a one-week experiment. The companies that see the best returns commit to at least three months and let the campaigns mature.
