- Joints pulling apart as timber shrinks
DIY sealant or a professional job?
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is, then guaranteed for a year.
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and does not move well, and getting the depth right matters as much as the look.
New build mastic for homes and businesses in Speen
We carry out plot mastic and second-fix sealing for builders, and snagging reseals for new-home owners. Both get the same care over preparation. If you have frame joints opening as the plaster dries and beads laid onto grit and dust from the build, we can help, whatever the surface.
For a small place like Speen, the journey and access are planned in advance, and the work itself is the same as on any site.
A 12-month guarantee comes as standard, so you’re not left on your own once the job is done.

For landlords and businesses
Failed sealant is one of the commonest items on a check-out report. Several properties can be quoted together.
Water getting past a failed joint can damage the building, which is a bigger problem in a rented property. Resealing at the right time is simple maintenance that we can handle for you.
Honest limits
To be straight with you, some problems need a different trade:
- Broken tiles or a split tray
- Cracking that points to a structural problem
- A tray or bath that isn’t properly supported, until it’s fixed
If in doubt, call 0345 464 0079 or drop us an email and we’ll say what we think before booking.

What the job involves on each surface
Bathrooms and en suites
En suite showers are a common source of leaks into the room below. Resealing properly keeps water where it belongs.
Windows and doors
Draughts around new frames are often a sealant gap. We check and reseal the frame edges.
The process
Before we leave, we go over the finished joints with you. The visit itself generally takes anything from a few hours to several days, depending on the number of plots, depending on how much there is to do. In a small place like Speen, access is usually the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- Each joint is checked for movement before work begins.
- We remove the failed sealant and clean the joints.
- We make sure the joints are dry and prime them if needed.
- Baths are filled with water, then the new sealant is applied.
- We check every joint and leave you with the cure times.
Getting ready for the visit

Signs you need new build mastic in Speen
Baths and trays settle under load once the home is lived in. A bath sealed empty drops slightly when filled, straining the joint and the sealant may split.
It’s worth asking for a quote if you see:
- Frame joints opening as the plaster dries
- Gaps opening as the house dries out and settles
- Leaking shower tray seals in a new home
- Cracked caulk along new skirting
Around Speen, as everywhere, new build mastic is only as good as the preparation behind it.
Questions to ask before booking
- How long to leave it before use
- Whether the sealant suits the joint
- What guarantee comes with the work
- Which colour the sealant will be
