One of England’s oldest towns
Towcester grew on Watling Street, where the Roman town of Lactodorum once stood, and it claims to be one of the oldest towns in England.
The old coaching inns along the main street, the racecourse at Easton Neston and the canal at Stoke Bruerne all sit within a few miles. Newer estates have expanded the town to the south, and the villages around are built in local ironstone and limestone.
Stone like this is beautiful and porous, so we use non-staining sealants and finish every joint carefully.

Copings, piers and stone-to-frame joints
Joints under copings and between stone and frames keep rain out of the wall. On stone, we use low-modulus, non-staining products and keep the bead neat, because it’s on show.
It’s the same care we’re taking on the natural stone façade at the new City of London law courts at Salisbury Square, where we’re on site now.
What we do around Towcester
Stone houses & cottages
Joints round frames, sills and copings sealed with non-staining products.
Bathrooms
Showers, baths and vanity tops resealed with anti-mould silicone.
Kitchens
Worktops and splashbacks finished neatly in a matching colour.
Movement joints
Brick, block and stone joints resealed with low-modulus sealant.
Modern bathrooms in old buildings
Barn conversions and cottage refurbishments often put crisp modern tiling and dark frames inside thick old walls. The joints between frame, tile and sill need to be sharp, and flexible enough to cope with an older building moving.
- Frames, reveals and sills masked and sealed
- Black, anthracite or tile-matched colours
- High-movement sanitary silicone in wet areas

Sealant matched to the wall
Where a marble vanity or worktop meets a painted wall, white sealant can look stark. We tint the sealant to match the wall so the line almost vanishes.
It’s one of those finishing touches that makes a refurbishment look professional.

Towcester sealant questions
Can you seal joints on stone walls and copings without staining them?
Yes. We use non-staining sealants on natural stone, mask where needed and choose a colour that blends with the stone.
Do you cover Silverstone, Roade and Blisworth?
Yes. All of the villages on this page are covered, including Silverstone, Roade, Blisworth, Stoke Bruerne, Paulerspury and Greens Norton.
Can you colour-match sealant to a painted or plastered wall?
Yes. We can tint the sealant to match plaster or paint where a worktop, vanity or panel meets the wall, so the joint almost disappears.
