From the initial quote through to the follow up inspection and check, I was happy with the work, the service from WindowTek was excellent. Everything was explained fully (and in plain English!), the fitting was quick, efficient and clean causing the minimum disruption possible. I was also consulted immediately with any potential issues and concerns and my needs as a customer were considered before any changes were made to the originally agreed plan.
In short, for the cost, but particularly the high standard of workmanship and customer care given, I would highly recommend WindowTek.

The guy that came around to survey the work to be done was very friendly and clearly knew what he was talking about. He came up with great suggestions on what may work best for us, and they did! The quote came through very quickly and was so reasonable we avoided the need to shop around and placed the order there and then. They worked around our other building works and fitted the windows exactly at a time that suited us, which was ideal.
The quality of workmanship was very high and everything was left neat and tidy. We would have no hesitation in using this company again and would be more than happy to recommend them to others.

My wife and I were very impressed by Ben and Trevor who worked quickly and dilligently: they were both a pleasure to have around our house. The finished porch looks excellent – a vast improvement on what it replaced (although I’m sure you found that easy!!!!).
The “Buy with Confidence” forms have been completed, highest marks having been given all round, and we will have no hesitation in recommending Window Tek whenever the opportunity arises.
Thank you Leigh and please pass on to Ben and Trevor our thanks for a job well done.

We would definitely recommend this company. Our entire experience gets 10 out of 10.
Having had a visit from one of the National companies with the hard sell lines that you see on Rogue Traders, WindowTek was totally professional at each stage - from the first visit by the salesman, to the surveyor, to the excellent work completed by the fitters. We were informed of each stage of the process and each appointment was kept to the letter.
We are absolutely delighted with our windows and doors.
