Bathroom Renovation Windsor

A bathroom is a small room with a great deal in it: drainage, water supply, ventilation, electrics, waterproofing and finish. Built in the wrong order, it gets opened up twice. We run it as one programme with one point of contact, and where the job moves a soil pipe, alters a floor or reaches into the roof, we deal with the approvals side too. This page covers what that involves for a Windsor property.

For Windsor, on London-derived ranges a full bathroom refit typically costs £6,000 to £20,000 or more; Berkshire work generally runs below that. GS Renovation Ltd, a building contractor based in Potters Bar, does the work in Windsor: we carry the tanking, plumbing and tiling as one contract, with the electrics certified by a registered electrician.

How the job runs

1. Free design visit at your Windsor home and an itemised quote.
2. Strip-out, then first-fix plumbing and electrics.
3. Tanking to the wet areas, then tiling.
4. Sanitaryware and second fix, with notifiable electrics certified by a registered electrician.

Thames Water is the undertaker for both water and sewerage here

Thames Water is the statutory undertaker for both water supply and sewerage across the Royal Borough of Windsor and Maidenhead. That matters when a bathroom moves rather than being replaced where it stands. A new soil connection, a change to a below ground drain, or work close to a public sewer brings Thames Water into the job alongside the council. We check what the existing drainage does before we price a new layout, because the fall on a waste run is not negotiable.

Housing in Windsor

The stock in Windsor runs to roughly 16,960 dwellings, 34% of them flats and 66% houses, built 22% before 1919, 8% between 1919 and 1939 and 68% after 1945. 30% of homes here are terraced; a terrace bathroom in Windsor vents front, back or up, never into a party wall.

In a listed building, a bathroom is more than a fit out

There are 177 individual properties and features listed within the Inner Windsor Conservation Area, forming 36 list entries. In the Trinity Place and Clarence Crescent Conservation Area there are 58 individual properties and features listed, forming 28 list entries, all at Grade II. That area is approximately 9.7 hectares in size and contains around 163 individual properties.

The Inner Windsor Conservation Area covers terraced rows on Sheet Street, Kings Road, Alexandra Road, Helena Road, St Mark's Road and Queen's Road, the villas and mews of Osborne Road, and the workers dwellings at Prince Consort Cottages. Where a property is listed, internal alterations can need consent in their own right, and that is settled before the first tile is ordered. We tell you which category your property falls into at survey, and we do not begin work that needs a consent nobody has applied for.

Where the bathroom sits in the house decides the difficult part

The council's appraisal describes buildings in the Trinity Place and Clarence Crescent area as three storeys in height, or two storeys with attics and basements. A bathroom two or three floors above the drain has a longer and less forgiving waste run, and the route it takes is a design decision rather than an afterthought. We set the pipework out before the room is stripped.

Occupancy affects it too. The Inner Windsor Conservation Area contains around 1,150 individual properties and over 1,500 individual address points, so a number of those buildings hold more than one address. Where a bathroom sits above or below someone else's rooms, access, noise, acoustic separation and the consequences of a leak all change how the work is planned. We agree that with you, and with whoever else is affected, before first fix starts.

Why Choose GS Renovation in Windsor

A bathroom goes wrong in the parts you cannot see: the fall on the waste, the tanking behind the tile, the extract that vents outside rather than into a void. We build those first and we do not cover them up before they have been checked. One point of contact runs the plumbing, the electrics, the tiling and the making good, and where the work is notifiable we coordinate the building control application and the inspection dates. Where the property is listed or sits in a conservation area, we settle the consent position before anything is stripped out.
