About our new build mastic in Rattar
Dust is the enemy of new-build sealant. We clean every joint thoroughly and prime where the surface and product need it, so the new bead bonds properly. Common call-outs are for plot mastic for developers ahead of handover and gaps opening as the house dries out and settles, across skirting & floors, bathrooms & en suites and plot handovers.
For a place like Rattar, the journey and access are planned in advance. Outdoor plot mastic needs dry weather, but indoor floor and skirting joints can be sealed whatever the forecast.
We stand behind the work with a one-year guarantee.

Joints and finishes in Rattar homes
Rattar is within about 1 mile of the coast. Plot mastic on new homes near the coast takes more weather than it would inland, so it’s worth checking at snagging. Timber frame is common in newer Scottish homes, and as the frame dries and settles, skirting and sealant joints can open up.
Whether the job is in Rattar itself or nearby, the right material for each joint matters as much as a neat finish. In and around Rattar, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.

DIY versus a professional finish
A careful DIYer can reseal a simple joint, 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.
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.

Different surfaces, different methods
Plot handovers
Good preparation at handover saves snagging later. We clean out building dust before sealing and prime where the product needs it.
Skirting and floors
As timber and screed dry, skirting and floors shift. We use a flexible product rather than caulk.
What affects the cost of new build mastic
Jobs vary more than people expect. What affects the quote:
- Whether there’s mould to deal with
- How easy the joints are to reach
- Whether old sealant or filler has to be cut out
- The type of sealant required
The cost depends on the size of the job, how hard the old material is to remove and access to the work. You’ll have a clear quote before any work starts.

To help us quote quickly, let us know:
- Access, such as stairs, a lift or height

Looking after it afterwards
To keep the joints looking good and working properly:
- Wipe joints with warm soapy water
- Keep water off fresh sealant until it has cured
- Act quickly if a seal starts to leak
- Watch for new gaps as the house dries out
Clean the sealant with a mild detergent and a soft cloth. Avoid abrasive pads and strong solvents as they wear the bead.
Mould takes hold quickly in sealant that has gaps or lifted edges. Resealing before mould gets in keeps the job straightforward.
The process
There’s no need to move everything out before we come, just the space around the work. Everything nearby is protected, and the work takes a few hours for most snagging lists, longer for a run of plots for a typical job. Outdoor work around Rattar depends on the weather, as sealant needs a dry surface, so an outdoor job can move if the forecast changes. Work indoors isn’t affected.
- We start by agreeing which joints are on the list, from the snagging sheet or plot schedule.
- Failed or untidy sealant is cut out completely.
- Surfaces are cleaned of building dust and primed where needed.
- New sealant suited to each joint is applied and tooled neatly.
- Each area is checked and left with its cure time.
Before we arrive
- Keep children and pets away from the work area
- Let us know about earlier repairs to the joints
- Mention any sign-in or site rules at work premises
