New build mastic in Penhurst
Failed shower seals, gaps along the skirting and messy beads are common items on a new-home snagging list. If you are still within the builder’s snagging or warranty period, tell them first, and if it is not put right, get in touch with us. We work on skirting & floors, windows & doors and kitchens, and people most often call us about cracks appearing as a new home settles and kitchen sealant that has pulled off the wall.
Somewhere as small as Penhurst, new homes tend to be conversions, self-builds or a few houses rather than an estate. Each still needs its sealant and floor joints finished properly.
A 12-month guarantee comes with the work, just as it does everywhere we cover.

New build mastic around Penhurst

In and around Penhurst, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint. For new homes near Battle station, it’s worth checking the sealant early, while snags are still fresh.

Should I try it myself first?
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is.
If you are set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it does not work out, we can still put it right.
Why it’s worth doing now in Penhurst
Running a new bead over the builder’s sealant might look tidy for a few weeks, but it can’t bond to what’s underneath. Taking it all out and starting again is the only way to get a lasting seal. Where a wall is exposed, as many are in small places like Penhurst, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
Rather than a set price list, we price the job in front of us: how many joints, what’s in them now and how we reach them. You will know the price before we begin.
Why choose Mr Mastic in Penhurst
- Trusted Arbo and Everbuild sealants
- White, clear, grey or another colour, product permitting
- Anti-fungal sanitary silicone in wet areas
- One-year guarantee on every job
Keeping the joints in good condition
Simple care keeps the joints in good condition. We recommend:
- Keep water off fresh sealant until it has cured
- Clean sealant with mild detergent, not abrasives
- Keep photos and emails about snagging items
- Get a leaking seal dealt with right away
Wipe the sealant with warm soapy water. Keep scourers and harsh chemicals off it as they wear the bead.
If a shower tray or bath seal splits in the first year, look for movement. Getting it resealed properly, and any movement checked, stops it recurring.
The process
When we get to you, we compare the joints with what we discussed. If we find something unexpected, we talk it through with you first. After that, the work takes anything from a few hours to several days, depending on the number of plots. In a small place like Penhurst, access is normally the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- 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.
Before we arrive
- Let us know about earlier repairs to the joints
- Mention any leaks or damp you’ve noticed
- Clear the area around the work
