New build mastic for homes and businesses in Laggan
If your new home has a leaking shower seal, open skirting joints or untidy sealant, we can help. While the builder’s snagging or warranty period runs, report it to them first, and if it isn’t put right, get in touch with us. If you are dealing with internal frame sealant that has split and smeared, uneven beads picked up at snagging, we can help, whatever the surface.
For a place like Laggan, the journey and access are planned in advance. Inside work goes ahead in any weather; outside mastic needs a dry day.
There’s a 12-month guarantee on every job.

What happens on the day
We work through the job in order: protection first, then preparation, sealing and a tidy-up. Typically it takes anything from a few hours to several days, depending on the number of plots. Around Laggan, distance and access matter more than parking. Let us know how to find you and how to reach the joints, and the visit is planned around that.
- Each joint is checked for movement before work begins.
- 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.
Before we arrive
- Move anything stored near the joints
- Mention any leaks or damp you’ve noticed
- Keep pets and children clear of the area while we work

Related advice
Looking after it afterwards
A little care helps the new joints last. We recommend:
- Raise failed sealant with the developer while you are covered
- Follow the cure time we give you
- Do not seal over failed sealant yourself
- Look at the sealant regularly in the first couple of years
Leave the sealant for the cure time we give you before showering or bathing. Most silicones need around a day to cure enough for use.
Leave a failed new-build seal and water can reach the floor and the ceiling below. Early resealing keeps the job small.
Honest limits
We won’t take on work that won’t last, so here’s what sealant cannot put right:
- Damaged fittings that need replacing
- Cracking that points to a structural problem
- Disputes or warranty claims with your builder
If in doubt, email us at info@mrmastic.co.uk and we’ll say what we think.

Do you need new build mastic in Laggan?
When the heating goes on in the first winter, the house dries fast. Gaps open along skirting, frames and worktops and cracks appear in the sealant.
People generally contact us when they notice something like this:
- Sealant work across a run of new homes
- Frame joints opening as the plaster dries
- New-build shower sealant that has already split
- Cracked caulk along new skirting
For jobs in and around Laggan, choosing the right material for each joint is as important as a tidy finish.
Questions to ask before booking
- Whether they’re fully insured
- What the cure time is
- Whether the sealant suits the joint
- What happens if the job turns out different
DIY versus a professional finish
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, then guaranteed for a year.
If you are set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it doesn’t work out, we can still put it right.
New homes and floors in Laggan
Timber frame is common in newer Scottish homes, and as the frame dries and settles, skirting and sealant joints can open up. Laggan is in the west of Scotland, which is wetter than the east, which means plot mastic and the sealant in new homes has to cope with a lot of rain.
In and around Laggan, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.

Common questions in Laggan
Will you come out to Laggan?
Yes, Laggan is covered. We work across all of Scotland, and smaller places are part of that. Longer journeys are simply planned in advance.
What guarantee comes with new build mastic in Laggan?
All our work, in Laggan and everywhere else, comes with a 12-month guarantee. We are also fully insured and ARBOMaster approved.
Can I send you my snagging list?
Yes. Send it with photos and we will quote for the sealant items. Items that need a plumber, tiler or the builder are flagged.
What colour sealant will you use?
That depends on what the joint meets: white or clear in most bathrooms, and a colour to suit worktops, frames and floors elsewhere. We agree the colour before any work starts.
What information do you need?
The location, the problem and the rough size of the job. If you can, email a few pictures.
Can new sealant go on top of the old bead?
No. The old sealant is cut out fully, the joint cleaned and primed where needed, before resealing.
Is it messy?
We keep the work tidy. We protect what’s around the joints, and the area is left clean when we finish.
Is there any odour?
Sometimes, a little. Any smell clears as the sealant cures, and ventilation helps.
Other services in Laggan
Why deal with it now?
It often makes sense to do all the sealant items on a snagging list together. You get one visit and one clear quote. 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.
Commercial jobs are quoted on the same basis as homes: the amount of work, the access and the products needed. Ask us for a quote and we’ll go through it with you.
What you get with us
- Experience in homes, commercial sites and hotels
- Quality sealants from Arbo and Everbuild

How the job changes by surface
Kitchens
Worktop, upstand and sink joints in new kitchens often get a hurried bead. We remove it and reseal with a kitchen-suitable sealant.
Plot handovers
Good preparation at handover saves snagging later. We clean out building dust before sealing and prime where the product needs it.
