First Rate Service

Due to "Which"recommendation, I decided to get a quote for replacement of all my windows. Tim (salesperson) provided a clear, informed presentation of the options available and even arrived with window samples for our inspection. No hard sale; price was provided after measuring up which was competitive. After obtaining two further quotes with other companies, I decided to proceed with APEX as they were responsive to my queries, informed and offered the best warranty. Their representative formerly measured up and the installation date agreed. A measure of a company is how they react when you encounter problems. There will always be issues that weren't envisaged and in my case several arose. I can however state that APEX dealt with them professionally and on a timely basis. The people, from the salesperson to the installers are first rate, decent personable people and a pleasure to deal with. No issue was too much for them. I have been left with a fantastic job and would highly recommend the company to others.

Window/door replacement

Apex replaced all our windows and two doors which was all completed in a week. We couldn't be happier with the end result. We have been truly impressed! Throughout the whole process we felt very comfortable with everyone we dealt with. There was no hard sell and every question was answered along the way. The installation process went extremely smoothly. Very efficient, tidy and skilled. Although we were not in any particular hurry the job was completed within a couple of months of the initial visit which was quicker than expected. We chose Apex to quote based on other favourable reviews and we have not been disappointed. Highly recommended !

Very good service

Initially quote was provided for all windows and front door, however only proceeded with the front door. This was because there was no option for a monthly payment. All staff seen (x3) were very helpful, kind, made helpful suggestions, pleasant and fitted my front door to a high standard, I am still waiting for a letter box, as one it it scratched and numbers as these were not provided although was on the order. Will return when can afford to change all my windows.

First class company, people and products

After suffering at the hands of a national company, I turned to Apex windows (Luton) to install 3 windows, French doors and a side door. From the ordering to the fitting, Apex windows provided a first class service. The product is just what we asked for, good quality, fair price and great support. A special mention goes to the two fitters, Damien and Corbyn, nothing was too much trouble for them and you could see that they cared about the job by the way the whole project was carried out with courtesy and care for the customer leaving me with an outstanding finish. Will I return to Apex? You can bet on it !! Mr M Bewley

Great and efficient Job

Great experience from start to finish. No pressure sales, listened carefully to what we wanted and worked from there. Lots of knowledge within their roles and good advice given. Josh and Luke the two fitters were very professional, polite and hard working. Cleaned up every day and kept us in the loop of what they were doing each day. We used Apex when they first started up as a company and having used them again, it is good to see and experience that same high standard and quality still in place. We would absolutely recommend this company and have already done so.

Very impressive installation team and sales rep

We started the process at the beginning of February and on the day of our enquiry the sales rep was able to fit us in and he took all the details, showed us our options and sorted out our requirements within 3 hours. The surveyor arrived a few days later and took all the necessary measurements on the 21st March the installers arrived and within 2.5 days the job was done! All the people from Apex were friendly efficient and helpful, the product was of a very high standard, the workmanship was excellent and we are very happy with the whole experience. We would confidently recommend Apex to anyone looking for a reliable and high-quality double glazing installation.

Fantastico!

Great product! We ordered a new composite door and glass surrounding. Although there where long delays, due to supply in Europe which was out of Apex's control, once delivered and installed we were very happy with the product. The after sales care as well is dealt with promptly¡ We now have a warm, cosy and secure home! Thank you Apex!

Excellent job

Our windows were completed last week from start to finish your company has been very good to deal with. No high pressured salesman and the window fitters did an excellent job. They cleared up themselves and there was no damage at all. We are very pleased with the windows and have no hesitation in recommending Apex.

Great work ethic

Second time we used Apex windows and the service level has always been exceptional. We have now done our whole house and have to say the front composite door has definitely made a difference on how warm our house gets now don't have to turn the heating on as often as before due to better insulation and keeping out the draughts. The guys who did the installation were great, clean and polite as always and the team in the office equally competent. Only one disappointment was we didn't get a discount for being return customers, maybe this is something the company ought to look at, but otherwise, we are very very happy 😊. Definitely recommend these guys if you want straightforward work no messing around, very legit and capable. We probably won't use them again for about 20 years or so as we're all done for now, But would definitely go back if/when we need any more work done. Thank you!

Your own checks

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.
