GS Renovation renovates bathrooms across Stanmore, fitting out the original bathrooms and creating new en-suites in the 1930s semis and interwar houses of HA7. With over 30 years of experience in Harrow and North West London, we deliver fully waterproofed, well-drained rooms that make the most of the space these period homes offer.
Waterproofing and wet rooms in Stanmore
A lasting bathroom starts behind the tiles. We tank and waterproof the walls and floor before tiling, so moisture cannot track into the structure of your Stanmore home. For walk-in showers and full wet rooms we form the falls correctly, seal every junction and set the drainage so water runs cleanly away. In interwar houses with suspended timber floors, this careful build-up matters even more, protecting the joists below from any long-term damp.
Good ventilation is part of the same job. Original Stanmore bathrooms were often poorly ventilated, so we fit effective extraction to clear moisture and keep the room fresh, which also protects the new finishes. We can add underfloor heating for comfort and to help surfaces dry, and we run the plumbing and drainage to modern standards. Bathroom electrics are notifiable under building regulations, so that work is certified as part of the project.
En-suites and space-saving layouts in HA7
The generous bedrooms in many Stanmore houses leave room to carve out an en-suite, and we plan these carefully so the new drainage and supply pipework routes sensibly without disruptive chasing. Where space is tighter, in a smaller box room or an awkward original bathroom, we design space-saving layouts with wall-hung units, compact showers and clever storage that make the most of every corner without feeling cramped.
We handle the full fit-out, from tiling and screens to sanitaryware, taps and lighting, choosing finishes that suit the age and feel of your interwar home. Because our own team runs the plumbing, the tanking and the electrics, the trades are properly coordinated and the room is watertight and warm when we hand it back. The finished bathroom is built to cope with daily family use for years to come.
