Called them out for one window replacement, gave me a good price and was happy once again

The whole exprian was great. Vik and the team were great. Everything was completed in the less time than what was quoted. I highly recommend Frontier Windows

Vik and his team were professional and friendly and all work was completed to a high standard.
I would highly recommend them.

Abysmal customer service and awful windows, we've had so many issues with them and 5 months later still not resolved, they completely ignore emails and phone call, stay well clear and save your money . Wonky windows not fitted correctly, we even had a window open the wrong way, iwould upload the poorly installed windows to see but it won't let me

Updated in response to the not so correct reply from Frontier:-
So its quite a phenomenon to receive a response from Frontier - albeit it took a poor review to prompt some sort of contact from them considering the massive amount of unanswered phone calls, messages and emails I have sent.
Firstly - I have never complained about the bathroom window being the wrong way around. However you did install the wrong glass originally regardless of the opening because you supplied frosted glass with lead when none of the rear windows has lead. I didn't mention this in the original review but as you are trying to use this as a reason to toot your own horn, I feel it only fair to correct you. That same window is still not finished either as all the expanding foam is still visible and the internal flashing hasnt been done. Something which has been brought to your attention multiple times.
Your replacement of 8 panes of glass "free of charge" was because by the admission of your various fitters and supervisors on the day, the lead was poorly and unevenly spaced - which you checked with a tape measure. The comment that you "allowed" us to retain a "substantial portion of the balance" is completely laughable. Firstly why would we settle the balance when you agreed it wasnt satisfactory & secondly you knocked off £50 per pane which amounted to £400 - for a nearly £9000 job i would hardly call that substantial.
The day you came to replace the panes, you were late. And you didn't replace them all as the top windows for downstairs bathroom were not on the van and the fitter said they would have to come again - which is why the lead doesn't line up with the larger panes. We have never confirmed the design, you were told on the day it still wasnt right.
You then sent an employee, I believe to be a manager or director (the gentleman who appears in your Facebook videos) who was meant to remove these panes, take them to the factory to rectify and then return. He came but they wasnt able to carry this out due to issues with the factory. He had a lengthy argument on the phone with someone at said factory and then informed my wife that he wasnt able to do as planned because the glass hadn't been made due to sickness. He was deeply apologetic in fairness to him and promised it would be sorted the following week. We were however on holiday so he said it would be upon our return. And this is what we are still waiting for. There are so many emails and messages sent to you so if you believe any of your own response to my review, why haven't you replied to my emails to say this?
The other issue with the inside trim of many of the panes not fitting correctly was also confirmed by the same man who took photos and said would be replaced when he returned. As well as finishing the bathroom flashing.
Again, if you believe your own version then why haven't you ever responded and why haven't you asked for the balance to be paid? There is evidence staring you in the face that these windows aren't finished or dont line up so im really not sure how you think you can argue the case. Emails and images have been sent with times and dates, they have never been correct since you did the installation.

Thank you Frontier Windows! Amazing service. Right on time and provided all the relevant information for what we needed

They’ve taken my deposit and disappeared. Don’t do it. I am currently going through fraud services to get my money back.

Highly professional staff- gave me the best advice with the problem that I was facing.

Excellent service, goes above and beyond for customers. Definitely recommended!

Very helpful staff and fast and efficient service . Offered reasonable quotes

I am giving them chance to rectify my issue and provide me with all.the certificate and insurance documents.
I hope the do that promptly.
If not I will explain whole sales tactics they use extremely poor quality fittings. Window not being balanced and a lot more to explain.
I will remove this review if all the issues are handled and sorted.
Thank you

Frontier Windows really changed the look of my house
Great service and good price. Professional company not like others
Thank you

The guys at Frontier Windows were very helpful throughout all the process.
My wife and I shopped around a lot and started with 5 quotes, their price came second and Anwais and Vik matched the cheaper quote.
We initially booked with them 7 windows to replace our current ones, and once we started our extension project they also provided 5 windows for the project.
There were some communication issues with their installers, but I have to say that they rectified it, and overall our experience was very positive.

I thought it was a great choice to go with this company. They got over 6 windows done in the nick of time. Even after they finished they assured us to check every window for touch ups. Of which they fixed to the best of their ability.

All involved from initial enquiry to fitting were helpful, professional and detailed oriented.

The whole process took less than 6 weeks from order to fitting.

The fitters were efficient, and ensured all work was done to a high standard

Really happy with the service we received. Sales pitch was good and not pushy didn’t feel forced in to signing up for a product we didn’t want, unlike another well known company we had come round to quote.
They called us when the windows were built and managed to fit us in the next day.
Two installers came to install the windows, they were extremely professional and without a doubt the cleanest work men I’ve experienced, I didn’t even need to hoover after they left.
Windows are good quality and look very smart.
Highly recommend.

From consultation to installation I received amazing customer service. I have gone through a few consultations with other companies for my double glazing and I have not felt more confident with my choice, everything was explained, concerns and pricing, were respected. I would highly recommend Frontier Windows

Great job! Friendly, efficient and highly professional. The newly fitted windows has given my home a completely different look and feel. Thank you once again to Vik and his team.

10/10 service!
I rang them and they came same day. They replaced my window in under 2 hours. Fabulous service. Definitely recommend.

Avoid Frontier Windows – Poor Quality, Communication & Customer Service
If you're considering Frontier Windows, think twice. We had several window replacement companies quote for our project, and unfortunately, choosing Frontier Windows was a mistake. The entire experience was frustrating, unprofessional, and stressful.

Poor Communication & Customer Service
From the start, communication was a major issue. After installation, they agreed that I could withhold £50 until a wrong window handle was replaced, promising to rectify it the following week. However, weeks went by with no follow-up or response. Despite multiple attempts to reach them, messages were either ignored or left on read with no reply.

Substandard Installation & Poor Workmanship
Window & Door Fitting Below Standard – The quality of the installation is far from professional. Handles are uneven, and one window came with the wrong handle entirely.
Serious Issues Left Unnoticed – A builder who was at my home for an unrelated job discovered packing materials hanging out from under two windowsills and four windows that had not been sealed, allowing water and cold air to seep in.
Front Door Draft Issue – The front door has a terrible draft, making our hallway constantly cold. After raising concerns about this, the second installer actually made it worse instead of fixing it.
Ignored for Two Months – Then Harassed for Payment
After chasing the company for two months with no response, one of the original installers finally returned to fix the outstanding issues. However, within 30 seconds of the work being completed, a salesperson was knocking on my door demanding the £50. This was immediately followed by three text messages asking for the payment. While I fully expected to pay for the job, this sudden urgency to collect money—after being ignored for two months—perfectly reflects the unprofessional nature of the company.

Final Verdict
Poor communication & lack of customer care
Unreliable follow-ups & ignored messages
Shoddy workmanship resulting in cold air leaks & drafts
No accountability for poor installation
Harassing behaviour for payment after months of neglect
I strongly advise against using Frontier Windows. They are unprofessional, their work lacks quality, and once they have your money, good luck getting them to fix anything. Save yourself the stress and choose a company that values its customers.

Vic was very helpful from the beginning and at each stage of the process - doing the quote, explaining the window designs and clearing all doubts. His team did a professional job completing the work in time with a great finish. Would definitely recommend .
