Waterproofing and wet rooms in Welling

A bathroom that lasts starts with what you cannot see. We tank and waterproof the walls and floor properly before any tile goes on, which matters in the interwar Welling houses where suspended timber floors need protecting from moisture. For a walk-in shower or a full wet room we form the falls correctly so water drains where it should, then tile over a sound, sealed substrate rather than trusting the grout alone to keep water out.

Drainage and ventilation are planned alongside the waterproofing. We make sure waste runs fall correctly to the existing soil stack on your DA16 semi, and we fit extraction that clears moisture so the room stays fresh and free of the damp and mould that plague poorly ventilated bathrooms. Underfloor heating is a popular addition, warming the floor and helping the room dry quickly after use through the colder months.

Space-saving layouts in interwar homes

The original bathrooms in Welling's 1930s semis are rarely large, so clever planning earns its keep. We rethink the layout to gain usable space, choosing sanitaryware and a shower enclosure that suit the real dimensions, and using wall-hung units and recessed shelving to keep the floor clear and the room feeling bigger than its footprint. Small changes to where the basin and WC sit often unlock a far more comfortable bathroom.

En-suites are a frequent request as families reconfigure the interwar upstairs, often carved from a corner of a main bedroom or a boxroom. We handle the new drainage, the concealed plumbing and the notifiable electrics, and tile and finish the room to match the standard of the rest of the house. Whether it is the family bathroom or a compact en-suite, we make every centimetre of a DA16 home work.

George was brilliant. Lovely bloke, very reasonably priced and a perfectionist to boot. He completed our small kitchen renovation with care and great attention to detail. I've already recommended him to others.

FAQ

Frequently Asked Questions about Bathroom Renovation Welling

How much does bathroom renovation cost in Welling?

There is no fixed price for bathroom renovation in Welling, because so much depends on your property and what you want to achieve. We survey first, then provide a transparent written quotation. Contact GS Renovation on 07472 424 226 for a free estimate. As a rough guide, bathroom renovation in London ranges from roughly £6,000 to £20,000 or more (indicative London ranges, MyBuilder and Checkatrade, 2026). Your figure depends on the size, specification and condition of the property, which is why we survey before quoting.

How long does bathroom renovation take in Welling?

A straightforward Welling project can be done in a couple of weeks, while a larger bathroom renovation with structural work runs longer. We set out a realistic, stage-by-stage programme before we begin so there are no surprises.

Why choose GS Renovation for bathroom renovation in Welling?

Welling homeowners choose GS Renovation for reliability and quality. We are fully insured, building control compliant where needed, and bring over 30 years of hands-on experience to every bathroom renovation project, with a single point of contact throughout.

Do I need building regulations for a bathroom in Welling?

Yes. Bathroom electrics in Welling are notifiable under Part P and must be certified, and any drainage, ventilation or structural changes must meet building regulations. We include certified electrical work and manage building control on every bathroom project.

Do you work on 1930s and interwar homes in Welling?

Yes. A large share of Welling's homes are 1930s and interwar properties, and we renovate them regularly. We plan each bathroom renovation around their particular characteristics, such as cavity walls, regular original layouts and the generous plots that suit extending, so the result suits the building and meets building control.

Can you fit an en-suite in my Welling interwar semi?

Yes, it is a popular project in DA16. We often carve an en-suite from a corner of the main bedroom or a boxroom in these 1930s semis, running new concealed drainage and plumbing back to the soil stack, tanking the wet areas, fitting extraction and completing the notifiable electrics. Careful space-saving planning makes even a compact en-suite comfortable and fully waterproof.

Do you cover all of Welling?

Yes. We work throughout Welling and the DA16 area, as well as the surrounding parts of South East London. Contact us on 07472 424 226 to confirm we cover your street.
