I recently bought my first house and the thing it was lacking was a porch and so I contacted Starglaze and they fitted me a porch, this now makes my house so special. Nothing was too much trouble and the efficiency was good.

We were in the market to replace our old double glazing...90's 'Leade Lights' stuff. Invited a major national supplier to quote, as we had had their windows in our house in Bristol. Almost predictably, the price started at something astronomic and worked it's way down via various supposed discounts. Final price was dependent upon our using their finance offer, at 17.9%APR. If not using the Bank of Robin Hood, the price rose by £2,900. Utter joke...we almost laughed. We then called in Starglaze. Different ballgame. Sales chap, measured, listened, made suggestions and gave us bottom-line price which was much more attractive. Long story short all was agreed and installation date given. I then gave Starglaze ops dept a minor heart attack by insisting that the installation was due to start 'tomorrow' rather than a month from now. They were very nice and didn't once suggest I was an idiot for completely misreading their letter. Installation was done, they arrived a day early and fitted 3 windows, much to our pleasant surprise. Tradesmen normally fail to turn up...never before had one turn up a day early. Bit of an issue at the factory, apparently, but windows were fine. They fitted all the rest, plus new patio doors. All went well except one upstairs window that, although it fitted, would not open correctly. Incorrect window left in place to keep house secure and correct replacement arrived following morning. The mark of a company is how it reacts to problems. Starglaze quite simply excelled. Nothing was too much trouble. They were nice guys, very polite, really got on with it and always left the place tidy. They do like their coffee, though... and it was a pleasure to keep them supplied. The installation was genuinely first class, and my total re-decoration time was less than 30 minutes for the whole house, (15 windows + patio doors), and only involved some minor touching-up of emulsion around the edges. A week or so later a window lock got stuck. One 'phone call and all sorted within 24 hours, (not a security issue). All upstairs windows are "Tilt & Turn", single pane and the extra light into the house.... without the horrible leaded lights... is incredible. As an added bonus, external noise levels inside the house have gone from low to darned near silent. These new windows are much more robust than the old ones. So, if you live in Lincolnshire or close and need new windows, just call Starglaze in Lincoln. We would recommend them to anyone, without reservation. All the staff we have spoken to are brilliant and seem to enjoy what they do. Sign of a good company.

Really pleased with our back door in the colour Chartwell Green. Very smooth open and close and security locking. Ordered and fitted within speedy time. Happy Days
Customer in Lincolnshire

We had all new windows and front and back doors. At no time were we made to feel pressured and they were excellent about us ordering and then putting the installations on hold until our funding came through. The installation teams were excellent and at no time were we left feeling that any problems they encountered were in any way our problems (we live in an old cottage). They just got the job done. They were very clean and tidy, making good each evening before they left. Prices were very comparable with other companies (even with the other companies' supa-special-one-day-only-phone-my-manager deals) and Starglaze's Georgian bars are a significant step up on many of their competitors. All in all excellent products and service, comparably priced. Have heartliy recommended them within our village, and everyone we speak with who have also use Starglaze have had similar excellent opinions.

How Much Is Double Glazing?

A standard 50cm x 50cm casement window begins at £250 but this will increase in price depending on the materials used; the shape; the style and the type of window.

Can I Get Double Glazing Installed in the Rain?

Double glazing can get installed in the rain, however, it’s important to think about the safety of the glaziers as well as the fact that there will be a hole in your home and your property is at risk of water damage because of this. It is recommended to get windows installed in dry weather.

How Long Does It Take To Get Double Glazing Installed?

From the moment you place your order, it will take four to six weeks to build and manufacture the parts for your bespoke window. On installation day, it can take anywhere between 3 hours to a full day depending on the materials used, the shape, size and the style. Number of windows will also increase the time.

What Types Of Windows Can I Get?

There are a wide variety of windows to choose from: Sash windows, flush sash windows, tilt and turn windows, casement (fixed and opening) windows, bay windows, bow windows and many, many more.
