Mastic man Barnet
Seven Seals is based in Barnet. Silicone and mastic sealing for kitchens, bathrooms, wet rooms, window frames and movement joints across High Barnet, New Barnet, East Barnet, Cockfosters, Totteridge and Whetstone.
Sealing work in Barnet
Barnet housing runs from Victorian and Edwardian terraces around High Barnet and New Barnet through to 1930s semis in Totteridge and newer flats along the Whetstone and Underhill corridors. Each brings its own sealing problems.
Older properties tend to need window and door perimeters resealed where timber frames have moved and the original mastic has cracked away. Newer flats more often need bathroom and wet room joints stripped and resealed where the original silicone was applied over an unprepared surface and has gone black within a couple of years.
Being based in EN5 means most Barnet jobs are a short journey — no travel charge, and usually a quicker slot than we can offer further out.
