How we handle new build mastic in Stonymarsh
Dust is the enemy of new-build sealant. We clean every joint thoroughly and prime where the surface and product need it, so the sealant actually sticks. If you have cracked caulk along new skirting and gaps behind new kitchen upstands, we can put it right, on plot handovers, bathrooms & en suites and windows & doors alike.
Older homes in small places like Stonymarsh often have timber floors that move with the seasons, which is why skirting and threshold joints need a flexible sealant, not filler.
All of our work is guaranteed for twelve months, and the guarantee is the same wherever you are.

What do you put in the joint?

Do you remove the old sealant?
Yes. We cut out all the old sealant and clean the joint before resealing.
Can you reseal over the builder’s sealant?
No. We always remove the existing bead, the joint cleaned and primed where needed, and a new bead applied.

- Deciding who is responsible under a builder’s warranty
- Plumbing faults behind the sealant
- Broken tiles or a split tray

When to call us in Stonymarsh
A new house holds a lot of water from the build, and it dries out over the first couple of years. Drying timber shrinks and pulls joints apart.
Keep an eye out for any of the following:
- Worktop and upstand sealant coming away
- Messy sealant that spoils new finishes
- Gaps opening as the house dries out and settles
- Skirting joints opening in the first winter
Around Stonymarsh, as everywhere, new build mastic is only as good as the preparation behind it.

What we do, step by step
Our applicators work methodically: protection first, then preparation, sealing and a tidy-up. For most jobs that takes a few hours for most snagging lists, longer for a run of plots and we leave things clean and tidy. For a village or hamlet like Stonymarsh, the journey is planned in advance: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.
- First, the list of joints is agreed from your snagging sheet or plot schedule.
- The failed sealant is removed completely down to clean surfaces.
- Joints are vacuumed and cleaned of building dust.
- Primer goes on where the surface and product need it, then the new sealant.
- Each bead is tooled and the cure times explained.
Preparing for the visit
- Tell us about any water getting in
- Let us know about earlier repairs to the joints
- Try not to wet indoor joints just before the visit

Why it’s worth doing now in Stonymarsh
For developers, getting the sealant right first time saves return visits. Every return visit for a failed seal takes time and most come down to preparation. Older cottages and farmhouses around Stonymarsh can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
A failed joint rarely gets cheaper to fix by waiting, because water and mould keep working on it. If you’re unsure, ring 0345 464 0079 or email us and we’ll give you an honest view and a quote.

Landlord and commercial work in Stonymarsh
Businesses can book us for washrooms, kitchens, offices and more. For commercial premises, we can talk through working times when we quote.
A neglected joint can let water reach the structure, which is a bigger problem in a rented property. Resealing at the right time is simple maintenance.
DIY sealant or a professional job?
If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it doesn’t work out, we can still put it right.
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and does not move well, and getting the depth right matters as much as the look.
