Excellent large conservatory Roof Replacement

We are very pleased with the standard of work and professionalism of Harwich Glass. The work was carried out in the indicated timescale and the workplace was kept very tidy each day. The team that worked on our project all were very polite and friendly and any small requests dealt with. We would have no hesitation in recommending this company, while this was a large job, we had a small window replacement dealt with in the same manor prior to that

Brillliant job.

We had spent quite a while and spoke to many comapnies about the New Hardwood windows we wanted and how we wanted them installed, our job was considered to be difficult , costly and unusual, so much so that many big name firms just flat refused to take the job. Harwich Glass showed no apprehension at al , turned up to survey and discuss the project and our exacting spec, went away put together a quote and then returned to do a 2nd survey and go over details to be sure we were all on the same page. They deliverd on the agreed dates and commenced work on the agreed date. the fitters were on time , clean and tidy workmen who completed the 3 days work efficiantly and with a genorus care to attention. Job completed half a day early and My Wife and I were invited to check over the install , we found 1 handle that was faulty but that was replaced and installed within 3 days. Price was great. Workmanship was Great, Punctuality Great. I was very happy to deal with a Firm that did a nice clean job, on time and to the agreed price and also delivering the quality we specified.

Gold service

We contacted Harwich Glass to remove 5 double glazed windows in our bungalow, including 2 big bay windows. The two fitters were amazing, polite, tidy and on time each day - 3 and completed a very good installation for us. I would recommend Harwich Glass to anyone looking for a top class job at competitive prices.

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.
