They did everything they could to make sure the job was done asap and they have me a really good price too. The work itself was done really well, the guys were lovely to have around and they cleaned up really well afterwards. Very happy customer! Highly recommend 👌

FAQs

How much noise will double glazing block out?

A significant amount. Modern sealed units noticeably reduce traffic and street noise, which makes a real difference on busier Sidcup roads.

Can you replace just the glass if my units have misted up?

Yes. In most cases we can fit new sealed units into your existing frames, which saves you the cost of a full replacement.

How long does a typical installation take?

Most homes are completed within a single day. Larger properties may need two, and we will confirm timings in your quote.

Will new double glazing lower my heating bills?

Yes. Energy efficient units keep warmth inside your home, so your boiler works less and your bills come down over time.We do. Hinges, handles, locks and failed units can all be repaired or replaced, and we always suggest a repair first where it makes sense.

Do your installations come with a guarantee?

They do. All our work is FENSA certified and covered by a guarantee, with a local team on the High Street if you ever need us.With quality frames and proper fitting, you can expect 20 years or more of reliable service, and we are just up the road if you ever need us.
