PVCu Windows


Lewes Home Improvements supply & install replacement PVCu windows across Sussex. Many of the windows that we currently remove are old 1st generation PVCu windows.


I am pleased to say that the standard of our new PVCu windows is a completely different class to that of the 1st generation of PVCu windows. The first PVCu windows on the market were badly proportioned with thick, square profile sections, ugly black gaskets around the glass & fitted with poor quality hardware. They were invariably no more secure than the original timber or steel windows they replaced, and architecturally stripped many buildings of characterful original windows.


We also supply & install PVCu sliding sash windows -



Slimmer profile sections


Whilst PVCu windows will not be suitable for every home, the Rustique & System 10 windows we install are the very best PVCu windows available. They are slimmer in profile than normal PVCu windows which gives a larger glass area & also improves the energy rating.  With link to profile section drawing. -

Or sprayed in any RAL colour   Ral colour chart



A choice of handle colours


We offer one of the widest choices of handle colours on the market. All our handles are offset to give you more clearance between the window frame & your hand. All our handles are locking & are keyed alike so one key opens all window handles on your house.

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.


We guarantee all installations comprehensively including all hardware (which is normally specifically excluded from most company guarantees). Please click here for our guarantee statement.
