Good all round job. Fitters prompt & professional. Lead sales personnel gave a fair price for service. Did not give inflated price.

The two guys worked well and the fitting was quickly done. They cleaned up any debris, did cement and pebble dash and did a good job with snagging (making good).

Had all my windows fitted by Blenheim. An excellent job by all. Very efficient from first appointment through to fitting. The fitters were here on time, very clean and tidy. The finish was superb. Am very pleased with the end result. A quality product and great customer service. Would definitely recommend. Lisa. Welwyn Garden City

Professional and efficient technicians transformed my Victorian terrace with new windows and shutters. The work was completed to a high standard and I would recommend Blenheim Windows to friends. Excellent work by them and complete satisfaction on my part.

We had every window in our house replaced, along with a new patio sliding door and french doors. We are pleased with everything and the fitter did a good job with installing the cassettes and adjusting the front and back doors. My wife had no hesitation in recommending you to her friend.

All the staff I dealt with were very helpful and friendly. All appointments were kept and on time. The unit was ready in a couple of weeks. The fitting was painless - very clean and tidy. Very good value for money.
