Conservatories

We design and install custom conservatories using A-rated energy-efficient materials. Our options include coloured frame, white PVCu, and contemporary styles, with online pricing calculators for transparency. Each structure is built to meet modern thermal standards while enhancing property aesthetics and functionality. Clients benefit from free surveys and fixed-price quotations.

Double Glazed Windows

Our double-glazed windows combine durability with thermal efficiency, featuring hook locking systems approved by insurers. Manufactured in-house, they include obscure glass options and come with a 10-year guarantee. Installation is handled by certified professionals, ensuring compliance with building regulations and long-term performance in diverse weather conditions.

Composite Doors

We supply and fit high-security composite doors with multi-point locking mechanisms. Available in various styles, including panelled and Rock Composite designs, these doors improve insulation and property value. Each installation includes a free survey, with options for side lights or top lights to enhance natural light entry while maintaining security.

Roof Replacements

Our lightweight tiled and glass lantern roofs transform outdated conservatories. The process includes removing existing roofs and fitting thermally efficient replacements in a single day. Clients receive fixed-price quotes after on-site surveys, with options to upgrade to full rectangular glass panels for improved aesthetics and light transmission.

Home Extensions

We construct brick-built home extensions with glass lantern roofs, featuring plaster-finished interiors and uPVC patio or bi-fold doors.

We had windows fitted by Top Line 4 years ago. Recently one of the windows had blown and their team came to repair it. Today one of their team came to re-mastic the seal on the window but also checked all the other windows at the same-time. I would have no hesitation in recommending Top Line for their fantastic installation and aftercare service for your windows and doors in Hampshire.

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. Clearly not reliable or worth dealing with so going to take my money elsewhere.

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.

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 and will make sure I never use This company nor will I recommend them
