Stop Draughts, Rattles & Condensation

We can upgrade your sash windows with draught proofing and slim double glazing. Eliminating draughts, rattles and condensation.

Keep Your Original Period Windows

We recognise the value and character of original joinery. Which is why we always restore and conserve where possible before offering complete replacement.

Save Money On Your Heating Bills

Less heat lost through your sash windows means lower heating bills for you. On average Envirosash customers save around 25% on their heating bills.

Reduce Noise into your Home

Combining draught proofing with double glazing will significantly reduce the amount of external noise intrusion into your home. Peace and quiet like you’ve never known it.

"The Envirosash team were brilliant, organised, prompt and value for money. They left our home clean, tidy and most of all warmer than they found it."

See Why Our Customers Love Us

“Other quotes said I would need completely new windows where Jabin said they could reuse the original frames and sashes which really got the cost down. I am very happy with their work and now the warmth of the room is amazing.” Mrs L. Stable - London

“Envirosash provided significant thermal and acoustic improvement without compromising the architectural character of our home.” David – North Oxford

 

“From the initial survey to the completion, we felt confident that we had chosen not just another double glazing company but one with consideration for traditional joinery skills and sensitivities towards period and heritage. The double glazing has been superbly installed and is unnoticeable in appearance. What is immediately noticeable is the temperature.” Mike D Saltwood - Kent

“Alex and his experienced team manufacture new sashes that are indistinguishable from the originals and they spare no effort in restoring even the most warped and defective 150-year-old boxes, thus saving the cost and dirt of total replacement.” Joe Earle - London
