Mastic man in Letchworth Garden City

Sealant jobs we do in Letchworth Garden City

Letchworth Garden City was planned from scratch, and it still looks it: tree-lined roads, cottages set behind hedges, and houses designed to sit together as a whole. That makes the detail around windows, doors and bathrooms more noticeable than in many towns. Mr Mastic covers Letchworth from our base in Crawley, resealing bathrooms and kitchens and replacing mastic on period and modern homes alike.

We cut out the old sealant, clean the joint back, and apply a fresh bead in a colour that suits the setting. For external work on the older houses, we can use a sealant that can be painted to match a frame. Our guide to window mastic explains the options for different frames.

Parker and Unwin cottages to post-war Radburn estates

First Garden City Limited was set up in 1903, and Barry Parker and Raymond Unwin became its architects. The first houses, Alpha Cottages on Baldock Road, were occupied in July 1904, and the 1905 Cheap Cottages Exhibition brought builders and architects to show ideas for low-cost housing. Early homes were modest cottages to the east of the centre, with larger individual houses towards Letchworth village to the south-west. Many show the Arts and Crafts influence the town is known for.

After the war came the Grange estate, started in 1947, and the Jackmans estate from 1959, built on the Radburn principle with footpaths kept apart from roads. The Lordship and Manor Park estates followed from 1971, adding private housing to the south. Norton and Willian, former parishes, are now part of the town.

Each era has its own weak points. Old rendered cottages have small window frames where mastic meets render and cracks as the walls move. Post-war houses have bathrooms refitted several times, often with layers of sealant. Newer homes have builder sealant that fails as they settle.

Our services in Letchworth Garden City

• Bathroom & kitchen resealing: Every joint in the bathroom and kitchen, from the bath edge to the worktop, stripped back and resealed with anti-fungal silicone.
• Window & door mastic: Cracked or shrunken mastic around window and door frames, sills and patio doors replaced with a weatherproof sealant.
