Frontier Windows Reviews 98

Very disappointing experience. The installation took a lot longer than planned. We got home to a job that had been left unfinished, which once completed, they had to return for remedial works because the finish was so poor.

We were not walked through the external finish before final payment, and only discovered the issues ourselves uneven mortar, messy sealing, cracks, damage and obvious poor patch repairs.

We’ve since had to get an independent contractor to fix quite few issues.

Communication has been poor throughout, particularly from Vik and the response to all of the issues was a £50 voucher. Their customer service and aftercare is extremely poor and impossible to resolve.

Would not recommend this company.

The men were very professional and work very hard . Very tidy and would definitely recommend to anyone .

Frontier Windows superbly handled a complicated request for a disabled friendly door that would accommodate an electric strike for a remote release door. The team helped find a suitable option and were flexible on days to install. Communication was great as was the speed of the order. Very good quality product and service. Many thanks to Vick and the team

Vic and Awaisa and team brilliant throughout my installation of new windows and front door thankyou such much

Honestly, so happy with the work. The grey looks amazing.
Good pricing. Good installation.
Quick guys! Awais and Vik were absolutely amazing and communication was first class.
Frontier Windows, did an awesome job.
Recommend to everyone

Vik and his Team did Window installations at my property as part of a refurb.

Vik and team did a great job ! My work wasn’t easy but they made the adjustments . The installers were really good and they finished the job

Very efficient. Fully explained process to me. Very quick turnaround. Turned up on the date as booked. Very tidy. Left the house clean. Explained everything to me and ensured I was happy with the windows before leaving.

DO NOT USE AT ALL COSTS.

They will take your money and not complete your job to a satisfactory standard.

They will offer you a warranty that they will never register.

The installer damaged all of our trims. They promised to replace them all and 5 months later still battling to make contact with frontier windows as they ignore all calls, messages and emails.

Half of our glazed windows have a weird residue on them which I am trying to get them to replace but once again they do not respond to you.

Avoid like the plague. Many other companies who might be a bit more money are going to be much cheaper in the long run.

From the initial quote to the final installation, the whole process was smooth and professional.

The installers arrived on time, were friendly, and carried out the work to a very high standard. Everything was fitted perfectly and they made sure to keep the area clean and tidy throughout the job.

My house looks absolutely gorgeous

We recently had our windows and doors replaced, and we’re very pleased with the results. The work was very nice and has completely changed the look of our house. It feels brighter inside, and the exterior has a much cleaner, updated appearance.

The workers were friendly, professional, and got on with the job efficiently each day. They worked well together, kept everything tidy, and made sure the installation was done properly. The new windows and doors fit perfectly and operate smoothly. Overall, it was a positive experience, and we’re happy with the quality of the finished work.

Excellent service and Quality product.
I am extremely happy the way they dealt from survey to finished job. Excellent Quality of windows and double doors Finesse in finishing is beyond imaginations.
Overall work well done.

Be aware, don’t pay fully until you are satisfied with the job.
Had windows and doors fitted in July 2025 and fitters were very professional and polite.
Georgian bars on some windows panes were missing. It was meant to have 3 but it only came with 2 also front door lock was supposed to be a security lock but it came with normal lock.
Fitters and office guaranteed that it would be all sorted by following week but that never happened.
Contacted them several times and always told that someone will come and fix it but no one ever did.
So haven’t been chasing them for a while because of health problems but I don’t believe they will do anything about it.
As soon as they have the second and last payment they don’t bother with customer service.
Also the Fensa certificate that were promised never arrived.
Obviously a comboys outfit so be aware that sometimes they will do as little as possible to maximise profits.
It shouldn’t have cost them much to rectify the windows bars as it was a factory mistake and not theirs so I believe the factory would have swallowed the cost of the parts, and they probably would have spent a couple hours fitting new glass panes which would just be labour cost for them.
Had this review up a couple months ago and company contacted me asking to remove it and they would come on 4 February 2026 to rectify problems.
Obviously this review is going back on as they haven’t came as promised and refused to answer phone, messages and emails.
If this happens to someone else which it will please don’t remove negative review until they fix your problem.

I recently ordered four windows, and the entire experience was excellent. The representative who came to my home was professional, knowledgeable, and easy to talk to. They took the time to measure everything carefully, explain my options, and answer all of my questions without any pressure.

The ordering process was simple and straightforward, and everything arrived exactly as discussed. It’s clear they value both quality and customer care. I’m very happy with how everything turned out

If you’re on the fence — just do it. The new doors completely transformed the look and feel of my home. Solid, secure, and beautifully finished. The installers were friendly, efficient, and clearly knew what they were doing. Everything fits perfectly and works flawlessly. Couldn’t be happier with the upgrade.

From the first call to the final walkthrough, everything was handled with professionalism and care. The team showed up on time, explained the process clearly, and completed the installation without any hassle. The windows look fantastic and you can immediately feel the improvement in insulation and noise reduction. It’s rare to find a company that delivers exactly what they promise — this one truly does. Highly recommend!

Title: Refund Only Processed After Credit Card Intervention

Review:
I placed an order with Frontier Windows Ltd and paid a £500 deposit. During the survey, the company confirmed they could not meet my requirements, and we mutually agreed to cancel the order. I confirmed the cancellation in writing within 7 days, in accordance with their Terms & Conditions, and was advised the deposit would be refunded.

Despite this, no refund was issued by the company. I sent multiple emails and a formal complaint by recorded delivery, but the refund was only recovered after intervention by my credit card provider under Section 75.

This experience highlights the importance of carefully checking customer service and refund policies. I hope Frontier Windows improves its processes to ensure other customers do not face similar delays.

Great quality windows, really happy with the installation and the team.
They were efficient, on time and just a lovely bunch; from the point of sale to installation.
Thank you guys

Excellent work and even better customer service! They came highly recommended and did not disappoint!

Thank you for all your help!

Great experience with Frontier Windows and excellent customer service. Would highly recommend to friends and family.
