Topline Windows and Conservatories is based in Waterlooville in Hampshire where we have been manufacturing in-house doors, windows and conservatories since 1980. We use our own experienced fitters and part of our remit is a full after sales service when we supply and fit all products. We also offer several types of Conservatory Roof Replacement and Flat Roof Glass Lanterns for new builds and refurbished flat roofs.
Topline Windows manufacture and assemble conservatories for clients in the counties of Hampshire, West Sussex and the cities of Portsmouth and Chichester. From this website you can choose the type of conservatory you would like, its size and additional options, and a guide price will be calculated for you.
If your current roof is of a flat roof nature it should be possible to fit a lantern to your existing roof subject to site survey and existing building regulation certificate. Our home extension range with glass roof lantern would be of a brick built nature on exterior walls, with a plaster finish to all inside walls and ceiling.

This intelligent glass reflects over 60% of the sun's solar energy so your new double glazed conservatory won't become unbearably hot in the summer. Solar glare is reduced too, creating a beautifully ambient environment. A combination of low emissivity inner glass and argon gas filling means our glass gives twice the insulation of ordinary double glazing.
Great looking, fast fitted, thermally efficient replacement tiled roof that can incorporate roof windows. This is a simple lightweight tiled roof perfect for replacing an old tired conservatory roof. It is extremely light and easy to install. Ventilated roof stops condensation problems other conservatory roof systems can suffer from.
Our home extension range with glass roof lantern would be of a brick built nature on exterior walls, with a plaster finish to all inside walls and ceiling. The floor would be self-levelled complete with skirting boards; a choice of white uPVC patio or French doors**; and double glazed windows to suit with inside window boards.

Recently had Topline replace two large windows in my son’s flat and a replacement conservatory in our house along with new back door and double patio doors.
Very pleased with the work completed - Ray and Lewis worked hard, were extremely polite, helpful and did a great job. Also electricians and plasterers were polite, punctual and completed a good job.
Very happy with our new conservatory with a lantern roof. Thank you.

What a waste of time. Phoned on the Monday to arrange someone to come out to take measurements for a replacement set of doors. Earliest they could come out was Friday. Guy turned up, looked at the damaged door, and then left to see what hinges he had in stock for the door, even though we told him that the door needed replacing and it had a crack in it. He left and have not heard a thing.
I spoke to the office, who said they would get him to call me. Heard nothing. I have now wasted a week waiting for this company to give me a quote, when I could have had someone else come out instead.

Recently brought a house that has had windows fitted by this company... Previous owners gave us all receipts and guarantees as they have 10 years on them
Noticed a problem with one of the windows and didn't even get as far as complaining about door lock.... so emailed and they have said it's not on the windows it's on the person who paid for the windows....
In one bit of the guarantee is states that it's not transferable but notice of transfer can be requested for a sum to be paid at the discretion of the company.... They have now said they will do that at a charge of £300!!!!
Absolutely ridiculous

Just had windows and doors replaced, and what a difference! The windows and doors are great quality. The fitters were very professional and polite, couldn't ask for a better team. Come upon a couple of hiccups due to covid, causing delay in door availability, but we were kept in the loop at all times. Wouldn't hesitate to recommend to family and friends.

We had an extension built and old dining room knocked through to make a large kitchen diner finished with bi-fold doors opening out onto our garden. Build went perfectly and cannot speak highly enough of how well we were treated throughout. Topline also fitted a new glass roof to our utility room and repaired some minor faults to existing windows around our home and even took the time to repair our front door. Prices for all work were fantastic. After care and follow up visits were done in a timely fashion and all work completed to a very high standard. Will definitely topline use again. Thank
