We have used RealSeal Home Improvements several times for replacement windows and doors to our property and we would not hesitate to use them again in the future. They were efficient, courteous and extremely clean workers whose workmanship was of a very high standard. We would not hesitate to recommend them."

Sue and John, Abergavenny

Realseal Home Improvements were recommended to my by a family member and I have no hesitation in passing that recommendation. Their work is carried out to a high professional standard. Their presence is unobtrusive and all work is speedily undertaken with the minimum of disruption and inconvenience. They are polite, friendly, trustworthy and are careful to clear away any mess and they left the premises in an immaculate condition. Their prices are fair and competitive and there is no "hard sell". I have employed them on two occasions and will be calling them back to undertake further work in the near future.

In 2013 I purchased a property that needed refurbishing. Realseal installed double glazed windows throughout the property (brown PVC outside and white PVC on the inside). Also they installed new soffits, boards, gutters and downpipes. This work was carried out to an excellent standard at a very competitive price. A year later Realseal installed all the glazing and doors for a large sunroom extension, again to a very high standard. This year they completed the garage with a new door and fitted new bargeboards and rainwater goods. The quality of the workmanship is very good, clean and tidy, and the after sales service is excellent. I am pleased to recommend this firm to anyone planning such work.

D.F. Evans, Abergavenny

Also a lovely and fitting blue composite door at the front and a PVC door to the rear. They were very professional, efficient and a please to work with from start to finish & they gave me great value for money, doing a perfect job.

Realseal Home Improvements, Many thanks for the excellent work you have done installing the new doors to our house. We will always be pleased to recommend you and if we need to replace anything else, you'll be our first port of call!"

Faith & Lawrence, Abergavenny

We ordered a composite door in Chartwell Green, some PVC French Doors, four PVC windows and a back door for our new home. Realseal Home Improvements were very professional, explaining the different options, providing a great service, leaving everything neat & tidy, and we are very happy with the results. Can't recommend them highly enough."

Alice, Llanddeusant

Following our builders recommendation, and looking at other companies products/prices. We selected Realseal Home Improvements to provide replacement and new french windows and an external door for a furnished cottage renovation. From the initial discussions, through to the selection of windows, fitting and after service, Realseal Home Improvements were very professional, thorough, reliable and tidy. Realseal Home Improvements guided us through the selection of windows and doors; their attention to detail was excellent, for example, colours of spacers in the double glazing units, colour of window handles and matching the symmetry of the upstairs french windows with a downstairs patio door, ensured that everything matched the cottage perfectly. Timescales of the installation were met and the removal of our old windows & doors were completed efficiently and tidily. Everything was thoroughly cleaned and polished, and when, 3 months later, we noticed a scratch on a downstairs window, Realseal Home Improvements immediately arranged a replacement without charge. Realseal Home Improvements were a pleasure to have working for us and more than fulfilled our expectations
