Conservatory

Unicorn Windows Ltd of Leighton Buzzard recently installed a conservatory for me. I am very impressed with their ‘Can Do’ attitude and the team works throughout out the installation period. The location of my property is set far back from main road and there is only a small walk path leading to my property which is difficult to carry all materials and tools, but with Unicorn Windows team work’s experience made the whole project ran smoothly and successfully. Unicorn Windows teams are polite, easy to communicate with and provide a good service after sale. The quality of conservatory’s frames, windows ,roofs and French doors are very good quality The workmanship in the term of brick layer and construction are excellent. I do not hesitate to recommend to anyone who want to build a high quality of conservatory with a reasonable price, The unicorn Windows Ltd of Leighton Buzzard will be the First Choice!

Excellent service for over 20 years

Another excellent experience with Unicorn Windows. We have used Unicorn for 20 years and they have always been a great company to deal with. The first job was replacement doors and windows for the back of our garage (also recommending a very good firm who installed an automatic front garage door), followed by multiple one-off replacement units when our pre-existing ones developed internal condensation, then new front and back doors and most recently completely changing out our time expired double glazing for triple glazing, bifold doors for the patio and a new porch, including replacing some tired looking fake pillars at the front door. With a 10 year warranty (much longer than most companies) we’ve always been delighted with their responsiveness when any niggles have arisen. The latest team worked very hard for the two weeks they were here and we are very pleased with the results (they even cleaned out a blocked gutter). Unicorn installed missing lintels over all windows needing them - something the original company should have done - and provided bespoke designs for the new porch, the bay window moulding and our arched window. Removing the Georgian bars at the back of the house has let much more light in, whilst retaining them at the front and side has kept the house in keeping with the rest of our road. We have no hesitation at all in recommending Unicorn Windows for any of your door or window requirements.

Professionalism from Beginning to End

I hadn't used this company before but wanted to use a local trader, who I know do lots of work in Leighton Buzzard. From the initial consultation , through survey and then fitting, I found all involved to be highly professional and a pleasure to deal with. The fitters took 2 days to replace all windows and patio doors, clearing up after themselves and were very pleasant to deal with. I have no hesitation in recommending them to anyone and would definitely use them again.

A really hardworking team

Unicorn replaced my kitchen windows with a type that opens from the bottom, to enable me to reach the handles. They also replaced some child lock hinges on my bedroom windows. The whole process was very smooth from the initial contact to the final invoice. Before the installation I had several queries which were answered very quickly and explained thoroughly. They always answered the phone. The fitters were very friendly and professional. They were tidy, quiet and respectful of my home. They went over and above to help me, taking time to adjust the handles and didn’t leave until I was completely happy. With the final invoice came a booklet explaining how to maintain the windows which I will find very helpful. A first class service from all the Unicorn staff I dealt with.

Replacement door panel - guarantee's work

8 year old front door had a blown glass unit which Unicorn agreed to replace. It wasn’t available when we had other work done, but were given some dates that weren’t convenient. We suggested last Thursday but Unicorn said they would confirm. Fitter arrive at 9am to our surprise, fitted the panel and left within half an hour. Very pleased with completed job.

Replacement patio door

Called into Unicorns' windows office as we had blown units and were delighted that we could get an estimate later that day. The surveyor came out a day or so later to confirm measurements. Given an estimated delivery time, which was acceptable. We were phoned to say they had a cancellation for the 13 June, earlier than anticipated, which we accepted. Fitters arrived on time at 08:30 and soon had the old UPVc unit out. They prepared the site and again had the new unit in and complete by 12:15. All rubbish was removed from the site, and a few cosmetic items were remedied. Very pleased with the installation and the operation of the new unit.

Rapid, superb service

A problem with the handle of an exterior door fitted in 2023 led me to ring Unicorn at 8.30 this morning. Within two hours the component had been replaced. This is exemplary service and deserves the fullest praise.

Fantastic job

Unicorn Windows did a really terrific job for us, this is the 2nd time we used them + can’t recommend them enough. We had a new modern style front door plus a half glazed side panel fitted + it looks fantastic - it’s totally updated the front of our house. The locking system is so good, easy to use + v safe with a good number of latching points; it feels v secure. The 2 guys who did the fitting were hard workers, diligent, friendly as well as clean + tidy; they just got on with the job. Unicorn prices were v v reasonable. We shopped around + were given other quotes elsewhere most of which were twice the price with nowhere near as trendy a range. Very happy to recommend them.

Brilliant Customer Service

Unfortunately had a break in and needed to secure the broken glass panel in the front door. Within 30 minutes of making a phone call David was round measuring up to make the door secure until replacement glass available. He returned within the hour to install a security panel and took away the old frame. Glass panel arrived earlier than expected and installed 3 days later. David was very understanding of our situation and workmanship first rate. The super efficient response helped to ease what had been a traumatic few days. Pricing was also very reasonable.

I wish every contractor was this easy and pleasant to deal with

I called unicorn windows to replace a misty single window but then discovered we also needed a new front door handle which the engineer went and got and repaired the same day. I then had reason to call them again due to finding 2 more misty windows. They called me to let me know when the glass was ready and came at a time that suited me. It's always really easy to get hold of them and everyone is pleasant and just does what they say they will, when they say they will without over-charging. They also adjusted another window for me free of charge. Super easy and stress free. Would highly recommend.

Replacement of Cloakroom Window

Our 40 year old, double -glazed, metal framed window needed replacement. Unicorn Windows responded quickly to my call for a quote and once I agreed, they arranged the delivery and installation within a very short space of time. The installing team were polite, friendly and efficient. They got-on with the work in a timely fashion, and cleaned-up before leaving. We are very happy with the job.

What to check before you hire

Worth checking yourself
Always confirm credentials and quotes with the business directly before hiring.
Be wary of high-pressure 'today-only' discounts and a salesperson who won't leave. A reputable window or door firm gives you a written, itemised quote you can take away and compare against others.
Never pay the full price up front; a modest deposit with the balance on completion is normal. Ask what deposit protection or insurance-backed guarantee you get if the firm stops trading before fitting.
Get the specification in writing (frame material, the glazing units and their energy rating, and any trickle vents) so you can check you got what you paid for.
