Mastic and sealant work in Sawbridgeworth

Sawbridgeworth packs a remarkable amount of old building into a small town. The parish has around 159 listed buildings, many of them from 1700 or earlier, sitting alongside converted maltings, Victorian streets and later family housing. Mr Mastic covers the town and the hamlets around it from our base in Crawley, looking after bathroom, kitchen and window sealant in all of them.

Whatever the age of the building, a good seal depends on getting the old one out. We cut and scrape away the failed bead, treat any mould, clean the surfaces and let the joint dry before applying new sealant. Mould that keeps coming back is nearly always a preparation problem, and our guide to why sealant goes mouldy explains what to look for.

Bell Street, Knight Street and the maltings

Much of the town centre has been a conservation area since 1968. Around Bell Street, Knight Street, the Square and Fair Green you’ll see a mix of timber-framed and plastered houses, brick fronts and some weatherboarding, with buildings ranging from the sixteenth-century Market House to the eighteenth-century Red House. In houses like these, nothing is quite square. Walls bow, floors slope and frames have moved over centuries, so a sealant joint has to cope with uneven gaps and continuing movement.

Malting along the Stort Navigation was the town’s main trade from the eighteenth to the early twentieth century, and several of the big maltings buildings have since been turned into apartments or small business space. On the Essex side of the river, the Lawrence Moorings flats stand on the site of the old Walter Lawrence joinery works. Conversions like these often have bathrooms fitted into odd corners, against solid old walls or on new timber floors.

Around the old core, twentieth-century housing spread out, including the homes on Pishiobury Drive on part of the Pishiobury estate. Here the jobs are more familiar: tired bath and shower seals, kitchen worktop joints and replacement uPVC windows whose mastic has had its day.

Old walls, converted maltings and riverside homes

In timber-framed and plastered houses we choose a sealant that stays flexible, because the building will keep moving long after we’ve gone. Around painted timber windows, a paintable sealant lets the joint be decorated to match. We keep the bead tidy and narrow, so it suits the house rather than shouting about itself.

In the maltings apartments and other converted blocks, a failed shower seal can leak into the flat below or into business space on a lower floor. We look closely at tray corners, bath ends and screen bases, and we can arrange access through the managing agent. Homes near the river and the navigation can stay damp in winter, so outside we pay extra attention to sills and the lower corners of frames, where wet mastic gives up first. See our external joint sealing page for how we tackle those.

Antiques centres, commuters and rented homes

Some of the old maltings now house antiques centres and small businesses, and those buildings have staff toilets, kitchens and washrooms like any other workplace. Shops, cafés and pubs along Bell Street and Knight Street are in the same position. We can work around trading hours by arrangement.

Sawbridgeworth station sits on the line between London Liverpool Street and Cambridge, which keeps rented homes in demand. Landlords and letting agents call us between tenancies and when a tenant reports mould or a drip through a ceiling, and we can quote for one property or several.

How it works

  1. Call or email. Tell us what needs doing, where it is and anything about access. Photos by email help.
  2. Quote and booking. We quote clearly before anything starts and fix a day that works for you.

  4. Neat new sealant. Each joint gets the sealant that suits it, laid and smoothed to a tidy finish.
  5. Guaranteed work. You’ll know the cure time before we leave, and every job comes with a one-year guarantee.

What we do in Sawbridgeworth

  • 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.

Your questions about mastic work in Sawbridgeworth

Do you cover all of Sawbridgeworth?

Yes. We cover the whole town, including Spellbrook, High Wych and Lower Sheering, and nearby Harlow and Bishop’s Stortford.

My house is timber-framed and listed. Can you reseal the bathroom?

Yes. Indoor resealing is routine maintenance. We use flexible sealants that cope with movement, and we keep the work neat and narrow.

Can the sealant around my painted windows be painted over?

Silicone can’t be painted, so where a joint needs decorating we use a suitable paintable sealant and explain how it compares.

I live in a maltings apartment. Can you arrange access through the managing agent?

Yes. We’re happy to liaise with managing agents about access, parking and timing.

Why does the mastic on my riverside home fail at the bottom of the frame first?

The lower corners and sills stay wet longest, so old sealant breaks down there first. We cut it out and use a weatherproof sealant with the right joint depth.

How do you handle the uneven walls in old houses?

We size each joint as we go and use backing rod where a gap is deep, so the finished bead is even and has room to move.

Do you work for landlords and letting agents?

Yes. We reseal between tenancies and after tenants report mould or leaks.

Is the work guaranteed?

Yes. Every job has our one-year guarantee.
