New build mastic for homes and businesses in Mapledurwell
We work in new homes and on new-build sites across Mapledurwell. One shower or a whole phase of plots, the method doesn’t change: cut out, clean, prime where needed and reseal neatly. If you’re dealing with worktop and upstand sealant coming away and joints pulling apart as timber shrinks, we can help, whatever the surface.
Around Mapledurwell, older homes often have timber floors that move through the year, which is why skirting and threshold joints need a flexible sealant, not filler.
A 12-month guarantee comes with the work, just as it does everywhere we cover.

What happens on the day
At the end, we look at the finished work together and explain the cure time. The visit itself usually takes a few hours for most snagging lists, longer for a run of plots, depending on the amount of work. In a small place like Mapledurwell, access is generally 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 we start.
- We remove the failed sealant and clean the joints.
- We make sure the joints are dry and prime them if needed.
- New sealant goes in, with baths filled first so they’re at their heaviest.
- We check every joint and leave you with the cure times.
Getting ready for the visit
- For indoor joints, keep the area dry beforehand if you can
- Move anything stored near the joints
- Tell us about access, such as stairs, a lift or high-level joints

What we cannot put right
To be straight with you, some problems need a different trade:
- Deciding who is responsible under a builder’s warranty
- Leaking fittings rather than failed sealant
- Structural cracks in walls or ceilings
If in doubt, phone 0345 464 0079 or drop us an email and we will say what we think.
Joints and surfaces we work on
- Plot handovers
- Skirting & floors
- Bathrooms & en suites
- Kitchens
- Show homes
- Windows & doors
Keeping the joints in good condition
No joint lasts for ever, but care makes a real difference. Our tips:
- Use the extractor fan every time you shower
- Wipe joints with warm soapy water
- Act quickly if a seal starts to leak
- Look at the sealant regularly in the first couple of years
Keep photos of the joints and any snagging correspondence with your builder. It helps if anything else comes up during the warranty period.
Leave a failed new-build seal and water can reach the floor and the ceiling below. Early resealing keeps the job small and the new finishes intact.
DIY versus a professional finish
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 doesn’t work out, we can still put it right.
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is, and the work is guaranteed for a year.
Signs you need new build mastic in Mapledurwell
If plaster or screed was still damp when it was sealed, the bond suffers. On a busy site, joints are not always given time to dry.
If you can see any of these, it’s time to have the joints looked at:
- Gaps between new skirting and floors
- New-build shower sealant that has already split
- Smeared, uneven beads picked up at snagging
- Cracked sealant around new window and door frames
In and around Mapledurwell, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.

What new build mastic looks like in Mapledurwell
Rainfall in the South East is lower than in much of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.

What happens if it’s left?
If you’re still in the builder’s snagging or warranty period, ask them to put it right first. If it’s slow, or the same joint keeps failing, a proper reseal from a specialist is the next step. In a small place like Mapledurwell, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
