Timber alternative windows


Lewes Home Improvements offer a range of windows specifically designed to look exactly like traditional timber windows. Hardwood bespoke timber windows are very expensive costing around 2-3 times that of a PVCu option.  If you own a property that is not listed then our timber alternative windows can give you the look & feel of timber but at a significantly lower cost. They are also maintenance free & will never need painting. This type of window can suit all types of period property from a small cottage to a Georgian townhouse. They are available as casement & sash windows.

Flush sash- New


Our new flush sash timber alternative windows are the most suitable for replacing flush sash timber windows. See below the profile drawing for this product.

An industry leading ordering procedure ensures total client satisfaction


At Lewes Home Improvements we want every customer to be happy with their investment. In an industry where every item is bespoke manufactured it is vital to get every order right first time.


In order to eliminate any misunderstandings over orders we always provide a written detailed fixed price quotation followed after acceptance by a fully detailed order confirmation for the client to check over before anything gets manufactured. This ensures that we make exactly what the client wants and avoid any disappointment or misunderstanding. Lewes Home Improvements of course take full responsibility for overall sizes.

Fitted with care by experienced installers


We install our windows with care & attention to detail. We follow industry best practice including always fixing frames with a minimum of 100mm masonry screws. We NEVER rely on insulating foam to fix a frame. We take care to install all frames square, level & plumb.


We trim internally & externally in trims colour matched to the window colour. We seal externally in neutral cure silicone colour matched to the window colour or clear against brickwork. Internally we seal trims with Stelmax liquid plastic for a wipe clean non discolouring finish. Should there be any minor plaster damage we re-plaster to leave a surface suitable for redecoration.



A reasonable price

At Lewes Home Improvements we believe our prices to represent very good value for money for the service we give and the quality of the products we fit.


We don’t guarantee to beat quotes from any other firm, but we will always quote our best fixed price we can carry out the work for.


We simply advise, measure & e-mail a quote. We respect our customers so we will never attempt to encourage a quick decision with phoney discounts or silly sales tactics.



Insurance backed guarantee for your peace of mind.

We fit a high quality product to the highest standards but should anything go wrong you will be reassured to know that our after sales service is also second to none.
