New Build Mastic in Somers Town
Plot mastic for developers and snagging failed sealant in new homes for Somers Town, backed by a 12-month guarantee. Call for a quick quote.
- Cracked sealant around new window and door frames
- Leaking shower tray seals in a new home
- Sealant that never bonded to the surface
Keeping the joints in good condition
How long the joints last depends on use and care. We suggest:
- Don’t seal over failed sealant yourself
- Put sealant faults on your snagging list early
- Ventilate bathrooms well, especially in the first year
- Get a leaking seal dealt with straight away
Leave the sealant for the cure time we give you before showering or bathing. Silicone is normally left for about a day to cure enough for use.
Do not let the snagging period run out with sealant problems unreported. After that, putting it right may fall to you, so raise it early.
About our new build mastic in Somers Town
A new build should have a neat, sound bead at every joint. Smeared, patchy or cracked sealant is worth sorting early, before water reaches anything behind it. Common call-outs are for skirting joints opening in the first winter and internal frame sealant that has split, across show homes, kitchens and plot handovers.
New flats are going up across London, many of them in larger developments. Snagging there often goes through the developer or managing agent, and failed shower seals, open skirting joints and gaps at thresholds are typical.
A one-year guarantee comes as standard, so you are not left on your own once the job is done.

Joints and finishes in Somers Town homes
Rainfall in the South East is lower than in much of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day. Much of London’s new housing is flats in larger developments, where snagging may go through the developer or managing agent.
If you’ve bought a new home near London Euston station, the sealant around baths, showers and frames is worth checking in the first year or two.

Fresh sealant can be knocked or cut by trades finishing off. If it’s disturbed before curing, the joint can be left weak and it shows once the home is in use.

- Sealant applied over dusty or wet surfaces
- Sealant work across a run of new homes
- Gaps between new skirting and floors
- Smeared, uneven beads picked up at snagging

Somers Town: your questions answered
Can you do new build mastic in Somers Town?
Yes. We work across London and the South East, and Somers Town is part of that. You can ring 0345 464 0079 or send us an email and tell us what needs doing.
Is parking a problem for a job in Somers Town?
In much of London, parking needs planning: a visitor permit or a bay close to the door helps a lot.
What sealant do you use?
Products from Arbo and Everbuild, among others, picked for each joint. We will tell you what we are using and why.
Is there a guarantee?
Yes, for a year. If there’s a problem with our work in that time, tell us and we will put it right.
When is the sealant fully cured?
Different products cure at different speeds, so please follow the time we give you when we finish.
I rent my home. Can I book you?
Yes, though it’s best to check with your landlord first. Landlords are often happy for the work to be arranged.
Do I have to be there?
Access is agreed with you when the job is booked. Indoors, that usually means someone at home.
Do you take out the old sealant first?
Yes. All of the old material is cut out and the joint cleaned before resealing.
What happens if it’s left?
Water getting past a failed seal in a new build reaches walls and floors that are still settling. Resealing promptly protects the new finishes around it. Damp from a failed joint spreads quietly in older London brickwork and timber, and by the time it shows on a wall or ceiling in Somers Town, the repair is bigger than the sealant job would have been.
What you pay reflects the work, not a rough estimate. That’s why we ask a few questions first and agree the price before starting.
