New build mastic for homes and businesses in Howwood
For builders and developers, we work through plots to the schedule you give us. We seal bathrooms, kitchens, windows, doors and skirting so plots are ready to hand over using the right product for each joint. Common call-outs are for shower seals failing in the first year or two and second-fix sealing on new plots, on show homes, bathrooms & en suites and windows & doors.
Around smaller Scottish places like Howwood, new homes tend to be single plots or small developments. Each needs its sealant and floor joints finished as carefully as on a big site.
The work is guaranteed for twelve months. If there’s a problem with our work within the year, let us know and we will sort it.

New build mastic in Howwood: local notes
The west of Scotland is wetter than the east, so there’s plenty of rain for plot mastic and the sealant in new homes to keep out. Timber frame is common in newer Scottish homes, and as the frame dries and settles, skirting and sealant joints can open up.

- First, the list of joints is agreed from your snagging sheet or plot schedule.
- The failed sealant is removed completely.
- Joints are vacuumed and cleaned of building dust.
- We prime where needed and apply a sealant suited to each joint.
- Each bead is tooled and the cure times explained.
How to prepare
- Keep pets and children clear of the area while we work
- Let us know about earlier repairs to the joints
- Tell us if parking is tricky

Why act early in Howwood
The builder is normally the first port of call while the snagging or warranty period runs. If it keeps failing or is not dealt with, we can reseal it properly. Exposed walls in smaller Scottish places take a lot of wind and rain, and once water gets behind a failed joint, damp in stone or harled walls is slow to dry out.
What you pay reflects the work, not a rough estimate. That is why we ask about the job first and give you a clear price before any work starts.

DIY versus a professional finish
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
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.
