9 Things to Look for When Picking Lincoln Window Companies
Searching for Lincoln window companies?
Picking the right one can quickly feel like a minefield.
Prices vary wildly, quotes are vague, and some firms disappear once the job’s done. Worse still, a bad installation can leave you with draughts, damage, and regrets.
With so many options and so much at stake, it’s easy to make the wrong call — especially if you’re basing your choice on price alone.
The good news?
There are reliable, experienced companies out there. You just need to know what to look for.
In this guide, we’ll walk you through the key things to check before signing anything — from reviews and materials to customer service and aftercare.
If you want quality windows, honest pricing, and a company that actually calls you back, keep reading.
What’s the Risk of Choosing the Wrong Lincoln Window Companies?
Not all Lincoln window companies are created equal — and choosing the wrong one can cost you more than money.
Poor window installation can lead to draughts, damp, leaks, and sky-high heating bills. In some cases, it can even void your home insurance if it doesn’t meet building regulations or isn’t done by an Assure-, Certass-, or FENSA-registered window fitter.
Then there’s the issue of cheap materials — some installers use low-grade or single glazing, which lacks proper thermal efficiency. Others might skip the basics altogether: think misaligned frames, broken window locks, or fitters who vanish once the invoice is paid.
And when things go wrong? Bad aftercare means you’re left chasing fixes or shelling out for full window replacements — often to repair mistakes that shouldn’t have happened in the first place.
The bottom line?
Choosing a reliable, experienced company may cost a little more upfront, but it’ll save you stress, time, and expensive regrets down the line. So before you commit, make sure the Lincoln window company you’re hiring has the track record, materials, and guarantees to back up the promises.
Because a perfect window isn’t just about how it looks — it’s about how well it performs.

How to Choose Between Lincoln Window Companies: 10 Things to Consider
With so many Lincoln window companies out there, it’s hard to know who’s legit and who just knows how to run Google Ads.
Before you hand over your hard-earned money, here’s what to look for.
1. Has a Strong Local Reputation and Excellent Customer Reviews
Reputation isn’t just about flashy websites — it’s about what real people say.
Look for genuine 5-star reviews on Google, Trustpilot, and even your local community Facebook groups.
Have they worked on homes like yours? Do people mention excellent service, tidy work, or a finished product that lives up to the quote?
Companies with strong local roots — not faceless chains — are more likely to care about customer satisfaction, provide accurate prices, and return your call when you need them.
Great Lincoln window companies often rely on word-of-mouth, so if your neighbour loved them, you probably will too.
Aperture Window Group is a great example — we’re a trusted local name with strong reviews and a loyal client base across Lincolnshire.
Our commitment to quality and honest pricing has made them a go-to choice for both homeowners and trade customers alike.
2. Shows Experience and Expertise in the Lincoln Area
Installing windows isn’t one-size-fits-all.
The best Lincoln window companies understand the quirks of local homes — whether it’s classic sash windows in the Cathedral Quarter or modern flush casement styles on a new build in North Hykeham.
Experience matters.
A company that’s worked offering Lincolnshire replacement windows for years will know how to navigate planning permission, listed building restrictions, and local building codes.
They’ll also have a better handle on timelines, installation quirks, and realistic costs for windows in this area.
Take Aperture Window Group, for example.
With over 20 years of experience in window installation, we know Lincoln homes inside out.
From heritage properties to full replacement windows for extensions, our knowledge of local materials and requirements sets us apart.
3. Offers a Full Range of Window Options (Not Just One Size Fits All)
The best Lincoln window companies offer a wide range of styles and materials — because every home (and homeowner) is different.
Look for companies that supply and fit uPVC windows, aluminium windows, timber-look windows, and hardwood windows. Ask about casement windows, French windows, sash windows, and even heritage-style double-glazed windows for period properties.
You want a team that can explain the energy efficiency, maintenance, and price differences between double glazing, triple glazing, and flush casement designs — not just push their most profitable products.
Aperture Window Group ticks this box and then some.
We supply a complete range of quality windows and doors, from hardwood sash windows to aluminium bi-fold doors to rooflights and bespoke windows.
Our flexibility means you get the perfect window for your home with a design you love.
4. Accreditation, Insurance, and Guarantees
Reputable Lincoln window companies should be fully accredited and insured.
Look for registration with FENSA, CERTASS, or Assure. This shows their work complies with building regulations and energy efficiency standards.
They should also carry public liability insurance in case of accidents or property damage.
Ask about their guarantees too.
Are you covered if something goes wrong with the installation? Do they back their double glazing units, glass for windows, or replacement windows with long-term protection?
Aperture Window Group is proudly Assure-certified and offers strong, clear guarantees on all installations.
Our commitment to quality standards gives you the peace of mind you should expect from any serious window company.
5. Clear, Transparent Quotes (No Hidden Fees)
No one likes surprise costs — especially when it comes to replacement windows or home improvement projects.
The best Lincoln window companies offer transparent pricing with VAT included, no hidden charges, and written estimates that clearly show what you’re getting.
Avoid vague “from £…” quotes or pressure to commit without seeing actual numbers.
A trustworthy team will explain your options, answer your questions, and give you the space to decide.
Aperture Window Group provides clear quotes, flexible packages, and real pricing based on your project requirements — not a sales script.
You’ll always know what your double glazing or bespoke window installation includes, from actual products to installation time.
6. Quality of Materials Used
Window fitters are only as good as the products they install.
Look for Lincoln window companies that use quality materials from trusted suppliers.
That includes A-rated double glazing, multi-chambered profiles for improved thermal efficiency, and eco-friendly products that support sustainable materials goals.
Ask about their partnerships — do they work with names like Rehau, Liniar, or other trusted UK manufacturers? Can they explain how their windows improve energy efficiency, reduce bills, and comply with regulations for replacement windows?
At Aperture Window Group, we’re proud to use high-quality materials that perform just as well as they look.
Our premium products are built to last — giving you a finished product that looks great, saves energy, and meets modern building regulations.
7. Aftercare, Repairs, and Warranties
Plenty of Lincoln window companies are happy to take your money — but what happens when something goes wrong?
A proper window installation should come with clear warranties and reliable follow-up support.
Whether it’s a broken window lock, a slight misalignment, or a pane that needs replacing, you want a company that answers the phone and gets things sorted — fast.
We stand by our work long after the final invoice.
At Aperture Window Group, we offer robust warranties on both products and workmanship, and if something needs adjusting, we’re just a phone call away.
Our goal isn’t just a great finished product — it’s long-term satisfaction and lasting relationships with every client.
8. Responsiveness and Customer Service
You can tell a lot about a company from how they treat you before you’ve signed a thing.
Good Lincoln window companies return your calls, reply to emails, and show up when they say they will. If the start is messy, the rest probably will be too.
Customer service isn’t just a bonus — it’s part of the job.
You want a team that respects your time, listens to your needs, and communicates clearly about everything from installation time to product choices and project requirements.
That’s why we’ve built Aperture Window Group around friendly, honest communication.
Our team keeps you in the loop from quote to clean-up. Because we believe excellent service is just as important as the windows themselves.
9. Do They Feel Like a Good Fit?
This one’s less about spreadsheets and more about gut instinct.
Do they listen when you talk? Do they explain things clearly without the jargon?
Choosing the right team isn’t just about ticking boxes — it’s about trust.
Lincoln window companies are working on your home — the one you’ve poured time, money, and care into. So yes, how they make you feel matters.
You should feel confident, comfortable, and respected from start to finish.
At Aperture Window Group, we know it’s not just about selling double-glazed windows or installing a bespoke home improvement option. It’s about being part of a project you care about.
And we take that seriously, with a team of experts who treat your home like it’s their own.
