Rosyth New Build Mastic
New build mastic across Rosyth and nearby, with old sealant always removed completely and a 12-month guarantee.
- Sealant applied over dusty or wet surfaces
- Internal frame sealant that has split
- Plot mastic for developers ahead of handover
How we handle new build mastic in Rosyth
We work in new homes and on new-build sites across Rosyth. Whether it’s one en suite or a run of plots, the method is the same: cut out, clean, prime where needed and reseal neatly. We work on bathrooms & en suites, skirting & floors and windows & doors, and people most often call us about shower seals failing in the first year or two and skirting joints opening in the first winter.
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.
Whatever the size of the job, it’s backed by our 12-month guarantee in Rosyth and across Fife.

What happens on the day
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 a few hours in a single home. In smaller Scottish places, parking is normally less of an issue than access and distance. Tell us how to find the property and how to reach the work, and the visit is planned around that.
- Each joint is checked for movement before we start.
- We remove the failed sealant and clean the joints.
- Joints are dried and primed where the product calls for it.
- New sealant goes in, with baths filled first so they’re at their heaviest.
- The finished joints are checked and the cure times given.
Before we arrive
- Keep pets and children clear of the area while we work
- On commercial sites, let us know about site rules
- Let us know about earlier repairs to the joints

Advice
When to call us in Rosyth
Sealant is often one of the last jobs before handover. Dusty, unprimed joints are common, so the bead never bonds properly.
If you can see any of these, it’s time to have the joints looked at:
- Skirting joints opening in the first winter
- Plot mastic for developers ahead of handover
- Beads laid onto grit and dust from the build
- Smeared, uneven beads picked up at snagging
If you’ve bought a new home near Rosyth station, the sealant around baths, showers and frames is worth checking in the first year or two.
Before booking anyone
- Which colour the sealant will be
- Is the old sealant removed completely?
- What preparation is included
- When the joint can take water or movement
Surface by surface
Kitchens
Beside the sink, the joint takes water every day. A kitchen sealant goes in there, food-safe where it’s needed.
Bathrooms and en suites
En suite showers are a common source of leaks into the room below. Resealing properly keeps water where it belongs.
What sealant work cannot fix
In fairness, there are a few things sealant will not fix:
- Baths and trays that move too much for sealant to cope with
- Cracking that points to a structural problem
- Disputes or warranty claims with your builder
If in doubt, send an email to info@mrmastic.co.uk and we’ll say what we think before you book.

Landlord and commercial work in Rosyth
We regularly work with letting and managing agents. Tell us the address, the job and how access works and we’ll quote.
Water getting past a failed joint can damage the building, which is a bigger problem in a rented property. Resealing at the right time is simple maintenance.

New build mastic in Rosyth: local notes
Rosyth is close to the coast. New homes near the sea put their outside mastic to work from day one, 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.
In and around Rosyth, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.

Common questions in Rosyth

Can you do new build mastic in Rosyth?

Do you remove the old sealant?

Are you an approved applicator?
Yes. We are ARBOMaster approved, the scheme for applicators of Arbo sealants.

Is there any odour?
There can be a smell while the sealant cures, which fades as it sets. Ventilation helps.

Do you work for hotels and businesses?
Yes. Commercial and hotel work is a large part of what we do. Working times can be discussed when we quote.
Should I try it myself first?
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
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, and the work is guaranteed for a year.
Aftercare tips
So the new joints stay in good condition:
- Watch for new gaps as the house dries out
- Clean sealant with mild detergent, not abrasives
- Act quickly if a seal starts to leak
- Wait for the cure time before using a resealed shower
Follow the cure time we give you before the area gets wet. Silicone is normally left for about a day.
Early snagging is easier snagging. Small faults turn into leaks if left in a busy bathroom.
