Double glazing

what'snext

I'm sure that there's probably a million old posts on double glazing but I'm afraid that here's another!

We're getting some windows replaced and have had three quotes for two windows:
1) Kommerling certass installer ~£1.3k
2) Aluplast certass installer ~£1k
3) Eurocell non-certass builder ~£850

We're going round in circles on which supplier to go with! Does anyone know how important certass installer or using a specific window company is? How do the Windows compare? I've been told that Kommerling and Aluplast are superior to Eurocell? I know that we can get building control to sign off the eurocell but we won't get the same guarantees as with the Kommerling or Aluplast installers...

Any advice gratefully received!

We've had Kommerling fitted to a Porch and have recently bought Kommerling French doors to be fitted later. We bought them on a recommendation from a friend who has many years experience in the trade and obtained us a really good price. We will get building control to sign them off if needed. The last house we sold we sold without building control for the windows and the purchasers didn't seem worried. We bought a house with two windows not having certificates but they comply from the details visible on the glass. The building regs are important for the creation of fire escape windows or escape route planning and money saving on K Glass. We've had other work done - fitting a new boiler and kitchen, bathroom and electrics and we have the building control certificates for them.

I don't know what you mean by 'certass' but its usual to go with a company who are Fensa approved, and issue a certificate saying it conforms to building regs. They also normally offer a 10 year warranty. This is what paperwork is expected when you sell. Obviously not everyone goes down this route, anyone can install windows and get them signed off by the building inspector, or indeed anyone can install windows htemselves without any paperwork ... but it is the norm.

I haven't got a problem with any of them although its been a while since ive heard aluplast mentioned. go for who you think will do the best job - come back if needed - recommended - been around a while - local . you can always get it signed off if fitted to a standard or an imdemnity cert later if needed.
