The Only Way is Extra

Kent’s favorite family-run home improvement business is now here in Essex

Due to our phenomenal growth in Kent, we have made the decision to bring EXTRA to ESSEX (It’s the only way!). We now have an Extra Windows office suite based in the heart of Colchester town centre. From our new base, we will be sending our reps out to every corner of Essex to introduce customers to the amazing choice Extra has to offer.

Extra Windows have been running for 17 years now and our family run business still has these family values at its core. We also have the highest quality range of windows, doors, conservatories and roof solutions on the market. All supplied and installed with a smile and our unbeatable 15 year insurance backed guarantee.
