Window and door installers win more enquiries by posting consistent, trade-specific content on social media… before-and-after photos, job-site proof and regulation reminders that build local trust without requiring a single viral moment. Show the work. Name the area. Let the jobs speak.
Last reviewed: June 2026. Updated with current UK glazing industry figures, FENSA compliance context and a practical social content plan for window and door installers.
Most window and door installers are booked solid Monday to Friday, then wonder why the phone goes quiet in January. The jobs are great. The photos are sitting on your phone. The problem is nobody sees them… and in a trade where homeowners spend weeks comparing quotes and checking reputations online, that invisibility costs real work. We work with trade businesses across the UK on exactly this, and social content is one of the simplest levers available to a fenestration installer who wants a steadier, better-quality pipeline.
Why social content matters for window and door installers right now
The UK glazing sector runs about 2,800–3,000 active installation businesses (IBISWorld, 2025), most of them small regional operators. There were 1.9 million residential glazing installations in the UK in 2024 (Sheerwater Glass, 2025), which means the demand is real… but so is the competition. When a homeowner starts looking at replacement windows or a new composite door, they go to Google first. Google holds around 93% of UK search traffic (Statcounter, 2025). 73% of UK homeowners search online before hiring a tradesperson, even when they already have a recommendation (Made for Builders, 2026). And 71% of consumers read online reviews regularly before choosing a local business (BrightLocal, 2025).
Social content feeds that research journey. A homeowner who sees your before-and-after in Stockport on Facebook, checks your Google profile and finds 40 genuine reviews, then reads a post about FENSA certification… that homeowner is already half-sold before they pick up the phone. The installer who is nowhere online gets skipped, even if their work is better.
What to post: the content types that actually generate enquiries
This is not a list of things that look nice on social. It is a list of things that move a homeowner closer to calling you.
Before-and-after installation photos
Two photos, a location, a product type, a completion time. That is the post. “Old draughty casements out, new A-rated uPVC in, Chorlton M21… done in a day.” Nothing flashy. The contrast does the work. Homeowners looking at their own tatty frames will stop the scroll every time.
FENSA certificate and compliance posts
Replacement windows and doors in England and Wales must comply with Building Regulations. A FENSA-registered installer (fensa.org.uk) can self-certify that compliance, notify the local authority and issue the homeowner a certificate they need when they sell. Most homeowners have no idea their cowboy quote comes with no certificate. Post about it once a month. “Every job we complete comes with a FENSA certificate… here’s why that matters when you come to sell.” That one post filters out price-shoppers and attracts serious buyers.
Job-location posts with the neighbourhood named
“Fitting four casement windows in Levenshulme this week… if you’re nearby and curious about replacing yours, drop us a message.” Simple. Targeted. It reaches exactly the people two streets over who have been putting off the call.
Honest cost education
A single uPVC casement window currently costs £350–£520 supply and fit at typical UK rates (Checkatrade, 2026). A full re-glaze of a three-bedroom house runs £8,000–£15,000 depending on specification (Checkatrade, 2026). A front door installation… supply and fit… sits at £500–£1,000 for uPVC (Checkatrade, 2026). Post ballpark ranges with honest caveats. “Prices depend on size, glass spec and access… here’s what most of our customers pay.” Homeowners who already understand the budget are far easier to convert to a quote.
Problem-identification posts
Show a rotten timber frame, a blown double-glazed unit, condensation between panes, a door that no longer closes flush. Explain what you replaced it with and why. This content reaches people who are sitting on a problem but have not yet started searching for help. You become the expert they already trust before they even know they need you.
Review screenshots and testimonials
A screenshot of a five-star Google review… with the reviewer’s first name and their general area… takes thirty seconds to post and builds more trust than a month of promotional copy. 88% of people who carry out a local search contact a business within 24 hours (BrightLocal, 2025). They want proof before they call. Give it to them.
How to choose content for window and door posts: a quick comparison
| Content type | Time to create | Best platform | Primary job it does |
|---|---|---|---|
| Before-and-after photo pair | 5 minutes | Facebook, Instagram | Proves quality; stops the scroll |
| FENSA / compliance explainer | 10 minutes | Facebook, LinkedIn | Filters price-shoppers; builds authority |
| Named-neighbourhood job post | 3 minutes | Facebook, Nextdoor | Reaches local homeowners nearby |
| Honest cost breakdown | 10 minutes | Facebook, Google Business | Pre-qualifies enquiries; saves quoting time |
| Review screenshot | 2 minutes | Facebook, Instagram | Social proof; builds trust before the call |
| Problem-spotting / red-flag post | 5 minutes | Facebook, Instagram | Educates; reaches passive researchers |
The minimum viable social plan for a busy installer
You do not need a content calendar, a scheduling tool or two hours a week. You need a phone with a camera and one repeatable habit: photograph every job before you start and after you finish. That is the content. Everything else is just a caption.
One post a week on Facebook is enough to stay visible in a local feed. Rotate between four types: before-and-after, review, compliance fact, cost range. That covers a full month on four posts. Pick one day… say Friday when the week’s jobs are done… and spend ten minutes posting what you did that week. That is the entire social strategy for a one-van installer who wants a steadier pipeline without hiring a marketing agency.
Pin three posts permanently at the top of your Facebook page: one that shows recent work, one that explains what FENSA certification means for the homeowner, and one that shows your reviews. Those three posts do the selling while you are on the tools.
What stops most installers from posting (and how to get past it)
The most common blocks are “I don’t know what to say” and “I don’t want to look like I’m showing off.” Both are easy to work around.
On not knowing what to say: you already know more about windows and doors than your potential customers. Any question a homeowner has ever asked you on a job is a post. “Can I get triple glazing on a standard casement?” “Does a composite door need a FENSA cert?” “How long does a full house re-glaze take?” Write the answer you give on site. Post it. Done.
On looking like you’re showing off: nobody who needs new windows thinks a before-and-after photo is bragging. They think it is evidence. That is what they came to social media to find. Share the work without apology.
If you genuinely want the social content handled for you… written, scheduled and posted consistently without you lifting a finger… that is part of what we build for window and door businesses at ContentWorks. You can see how it fits into the broader local-visibility picture at our guide to AI-assisted lead generation for window replacement installers.
Frequently asked questions
What should a window installer post on Facebook?
Before-and-after photos, FENSA compliance reminders, local job location posts and review screenshots. Those four types build trust and generate enquiries without paid ads.
They work because they show proof of real, local work. Homeowners comparing quotes want to see that you have done this job, in this area, to a standard worth photographing. Compliance posts additionally filter out the price-shoppers by making it clear your work comes with the paperwork that protects the homeowner when they sell.
How often should a glazier post on social media?
Once a week on one platform is enough to stay visible and generate enquiries. Consistent beats frequent every time.
Posting seven days a week for a fortnight then going quiet for two months is worse than one post every Friday without fail. The algorithm rewards consistency, and so do homeowners who see your name pop up regularly in their local feed. Pick a day, pick a format, repeat it.
Do I need a FENSA certificate for every window and door job?
Yes, for replacement windows and doors in existing homes in England and Wales. FENSA registration lets you self-certify Building Regs compliance and issue the certificate to your customer.
Without a FENSA certificate (or an equivalent from another competent person scheme such as Certass), the homeowner would need to apply separately for Local Authority Building Control approval. That is more cost, more hassle, and a red flag when they come to sell. FENSA registration is a genuine differentiator… post about it.
How much does it cost to replace all windows in a 3-bed house in the UK?
Most three-bedroom houses pay £8,000–£15,000 for a full re-glaze with uPVC casement windows, depending on size, specification and location.
Individual casement windows currently run around £350–£520 each supply and fit at standard UK rates (Checkatrade, 2026). Timber or aluminium frames, triple glazing and larger openings all push prices higher. London and South East rates typically sit at the top of any range. Publishing honest ballpark figures on social media pre-qualifies enquiries and saves time quoting for customers who cannot afford the work.
Is social media worth it for a small glazing business?
Yes, particularly Facebook and Instagram for residential installers. One consistent, location-specific post per week reaches homeowners in your service area at the exact moment they are researching.
The window and door purchase cycle can stretch weeks. A homeowner who first noticed your company on Facebook in October, saw three more posts in November, then called in December for a quote has already decided you are credible before the conversation starts. That is the value of showing up consistently: the sale happens before the phone rings.
What is the difference between FENSA and Certass?
Both are government-authorised competent person schemes that let window and door installers self-certify Building Regs compliance in England and Wales. FENSA is older and more widely recognised; Certass is an equally valid alternative.
Membership of either scheme means you can notify the local authority on the customer’s behalf and issue a compliance certificate without them needing separate Building Control approval. For social content purposes, the detail matters less than the simple message: “We are registered, your work will be certified, and you will have the paperwork when you sell.” That message closes more leads than any promotional caption.
Can I post price ranges on social media without undercutting myself?
Yes. Post ranges with honest caveats rather than fixed prices. “Most of our customers pay £350–£520 per window… final price depends on size, glass spec and access” sets realistic expectations without locking you into a number.
Homeowners who cannot stretch to the budget self-select out before they ask for a quote. Homeowners in the range already trust you for being straight with them. Either way, you save the quoting time and build the relationship. Price transparency on social is a confidence signal, not a discount signal.
How do I get more Google reviews as a window installer?
Ask within 48 hours of completing the job… by text message with a direct link to your Google review page. That timing, while the customer’s fresh-install satisfaction is at its highest, gets far more responses than a later request.
The numbers back this up: 71% of consumers read reviews regularly before choosing a local business (BrightLocal, 2025) and 88% of people who carry out a local search contact a business within 24 hours. Your reviews are not an afterthought… they are the filter through which every future enquiry passes. Post review screenshots on social. Ask for reviews on every completion. Treat them as part of the job, not an optional extra at the end.
The visibility gap most installers never close
Social content is one half of the equation. The other is making sure new customers can actually find you when they search. Social builds trust with people who already know you exist. Local search… your Google Business Profile, your reviews, your position in the map pack… reaches the homeowners who have never heard of you and are searching right now.
The installers who consistently win the best residential work combine both: they post enough to stay visible in local feeds, and they actively manage their presence on Google so they show up first when intent is highest. That joined-up approach is at the core of how we help trade businesses build pipelines that do not depend on word of mouth alone. If you want to see where your window and door business currently stands in local search, the free Visibility Scorecard gives you a clear picture in about four minutes… and tells you exactly where the enquiries are slipping past.
