About our new build mastic in Woolstone
For builders and developers, we work through plots to the schedule you give us. Bathrooms, en suites, kitchens, frames and skirting are sealed ready for handover. Common call-outs are for kitchen sealant that has pulled off the wall and untidy sealant flagged on a snagging list, on windows & doors, show homes and kitchens.
Where new homes go up in smaller places like Woolstone, it’s often a small development or a single plot. Each still needs its sealant and floor joints finished properly from day one.
The work is covered for a year after we finish. If anything is not right with it, phone 0345 464 0079 or email us.

How to look after the new joints
So the new joints stay in good condition:
- Get a leaking seal dealt with straight away
- Don’t seal over failed sealant yourself
- Look at the sealant regularly in the first couple of years
- Keep pictures and emails about snagging items
Wipe the sealant with warm soapy water. Keep scourers and harsh chemicals off it.
A failed seal in a new home lets water into joists, plasterboard and ceilings. Catching it early keeps the fix to the sealant and protects the rest of the house.
Should I try it myself first?
Sealing over old silicone is the commonest DIY error. New silicone won’t bond to old, so it lifts and traps water and mould underneath. Everything old must be removed first.
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions, then guaranteed for a year.
Questions from Woolstone
Is Woolstone in your area for new build mastic?

Is Woolstone within the area you cover?
Yes. Woolstone is within the area we cover, which takes in towns, villages and rural addresses. We work across London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
What colour sealant will you use?
White and clear are the most common, but sealant comes in other colours too. We match the colour to the finish before we begin.
Is it worth trying it myself?
That depends on the joint. High-level, external movement and fire-rated joints are professional jobs.
Are you fully insured?
Yes, we’re fully insured for domestic and commercial work.
My new home is still under warranty. Should I contact you?
Report it to the builder first while you’re covered. Once that’s done, or if they will not put it right, we can reseal it properly.

Can you quote for more than one area?
Yes. More than one area can be quoted together.
How it works
We work through the job in order: protect, prepare, seal, tidy. Typically it takes a few hours in a single home. In a smaller place like Woolstone, parking is seldom the issue; lanes, gates and long drives are worth mentioning. For outside work, side access and the height of the joints help us plan.
- We go through the snagging list or plot schedule and agree the joints to do.
- Failed or untidy sealant is cut out completely.
- Surfaces are cleaned of building dust and primed where needed.
- A sealant chosen for each area goes in and is tooled smooth.
- Each area is checked and left with its cure time.
How to prepare
- Mention any leaks or damp you’ve noticed
- Mention any sign-in or site rules at work premises
- Move anything stored near the joints

Why deal with it now?
For developers, getting the sealant right first time saves return visits. Snagging visits for failed sealant cost time on every plot. Homes in smaller places like Woolstone can face more weather, and failed outside joints let damp into walls. Inside, a split seal lets water into floors and panels just as it would anywhere.
A few things move the cost up or down: how much old sealant there is and how stubborn it is, any mould to treat, and whether we need extra access for height. We take all of that into account in your quote.

What we are called out for in Woolstone
New homes are full of moisture from plaster, screed and concrete, which takes a year or two to dry out. Drying timber shrinks and pulls joints apart, and sealant that can’t keep up splits.
The most common problems we see are:
- Cracks appearing as a new home settles
- Shower seals failing in the first year or two
- Plot mastic for developers ahead of handover
- Smeared, uneven beads picked up at snagging
Around Woolstone, as everywhere, new build mastic is only as good as the preparation behind it.
