New build mastic for homes and businesses in Letham
Building dust is behind a lot of failed new-build sealant. Each joint is cleaned of dust and primed where the product calls for it, so the new bead bonds properly rather than sitting on a layer of grit. Typical jobs include joints pulling apart as timber shrinks and untidy sealant flagged on a snagging list, across skirting & floors, windows & doors and show homes.
Timber frame is common in newer Scottish homes, and it settles over the first years, which shows as gaps at skirtings and floor joints. In older homes, timber floors move through the year too.
There’s a 12-month guarantee on every job, whatever its size.

How we quote for new build mastic
The price is agreed before any work begins. It’s based on:
- The amount of work
- Any working-time requirements on site
- How many areas need sealing
- The product the joint needs
Homes and businesses are quoted the same way: the amount of work, how we reach it and what it needs. Ask us for a quote and we will explain what it covers.
What we need to know
Before you ask for a quote, have a think about:
- The rough size of the job
- A few photos by email, if you can
- Where the job is, and your postcode
- What the problem is, such as mould, gaps, leaks or cracking

Aftercare tips
To keep the joints looking good and working properly:
- Check bath and shower seals every few months as the house settles
- Act quickly if a seal starts to leak
- Keep water off fresh sealant until it has cured
- Wipe joints with warm soapy water
Wipe the sealant with warm soapy water. Keep scourers and harsh chemicals off it as they wear the bead.
Do not let the snagging period run out with sealant problems unreported. Once it ends, the repair may be down to you.
Why act early in Letham
The builder is usually the first port of call while the snagging or warranty period runs. If it’s slow, or the same joint keeps failing, a proper reseal from a specialist is the next step. Exposed walls in smaller Scottish places take a lot of wind and rain, and damp in stone or harled walls takes a long time to dry once water gets behind a joint.
Instead of a standard rate, we price the job in front of us: how many joints, what’s in them now and how we reach them. The price is agreed before we begin.

For landlords and businesses
Water getting past a failed joint can damage the building, which matters even more when someone else lives there. Resealing at the right time is simple maintenance.
Failed sealant is one of the commonest items on a check-out report, and it’s easy to sort out between tenants. We can quote for more than one property at once.
New homes and floors in Letham
Timber frame is common in newer Scottish homes, so skirting and sealant joints can open up as the building settles.

What happens on the day
A visit follows a simple pattern: we look at the joints together, mask and protect the surrounding surfaces, do the work and tidy away. It normally takes a few hours for most snagging lists, longer for a run of plots. Outside jobs in Letham need a dry day, because sealant will not bond to a wet joint, so an outdoor job can move if the forecast changes. Indoor work goes ahead whatever the weather.
- We start by agreeing which joints are on the list, from the snagging sheet or plot schedule.
- The old bead comes out in full, with no layer left behind.
- We clean off dust from the build and prime the surfaces where the product needs it.
- New sealant suited to each joint is applied and tooled neatly.
- We check every joint and tell you how long each needs to cure.
Before we arrive
- Mention if the joints have been sealed before
- Where the joints are inside, avoid wetting them before we arrive
- Let us know if you’ve seen damp or leaks

Can I do it myself?
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions, then guaranteed for a year.
