New build mastic in Sullom
A new house keeps drying out and settling for its first couple of years. Timber shrinks, plaster dries and baths and trays bed down, and sealant applied in a hurry at handover can split. We’re often asked to deal with sealant that never bonded to the surface and untidy sealant flagged on a snagging list, on windows & doors, show homes and bathrooms & en suites.
For a place like Sullom, the journey and access are planned in advance. Inside work goes ahead in any weather; outside mastic needs a dry day.
A 12-month guarantee comes as standard, so you’re covered after we’ve gone.

Common problems we fix in Sullom
If plaster or screed was still damp when it was sealed, the bond suffers. On a busy site, joints are not always given time to dry first.
These are the problems we’re asked about most:
- Leaking shower tray seals in a new home
- Joints pulling apart as timber shrinks
- Internal frame sealant that has split
- Gaps between new skirting and floors
For jobs in and around Sullom, choosing the right material for each joint is as important as a tidy finish.

DIY sealant or a professional job?
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it does not work out, we can still put it right.
What happens on the day
Every visit runs the same way: we look at the joints together, protect the area around them, do the work and tidy away. Most jobs take anything from a few hours to several days, depending on the number of plots. Outdoor work around Sullom depends on the weather, as sealant needs a dry surface, so external jobs may need to move if the day turns wet. 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.
- Surfaces are cleaned of building dust and primed where needed.
- We apply a sealant that suits each joint and tool it to a neat finish.
- Each area is checked and left with its cure time.
Getting ready for the visit
- Let us know if you’ve seen damp or leaks
- For indoor joints, keep the area dry beforehand if you can
- Keep children and pets away from the work area

Quotes for new build mastic in Sullom
Every job gets its own quote. This is what makes a difference:

- Working hours on commercial sites
What you pay reflects the work, not a rough estimate. That’s why we ask about the job first.
Asking for a quote
Photos by email are helpful but not essential. Please mention:
- The type of property
- How we’d reach the joints
- How many joints, rooms or windows are involved
- Any previous sealing or DIY work
There’s no standard price list, as no two jobs are quite the same. Instead, we give you a clear price for your job. To arrange one, email us at info@mrmastic.co.uk.
When something else is needed
A few problems are outside what sealant work can do:
- Deciding who is responsible under a builder’s warranty
- Damaged fittings that need replacing
- Leaks from pipes, valves or wastes, which need a plumber
Not sure which it is? You can send an email to info@mrmastic.co.uk and we’ll tell you honestly before booking.

What new build mastic looks like in Sullom
Sullom 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. Work on the islands has to be planned around ferry crossings and the weather, so give us as much notice as you can.
In and around Sullom, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.

Keeping the joints in good condition
To keep the joints looking good and working properly:
- Check bath and shower seals every few months as the house settles
- Keep photos and emails about snagging items
- Resist patching a failed seal with a tube from the DIY shop
- Follow the cure time we give you
Do not stand on the bath edge or the lip of the tray while the sealant cures. Report any movement in a bath or tray.
Don’t let the snagging period run out with sealant problems unreported. After that, putting it right may fall to you, so raise it early.

Can I do it myself?
You can, for simple jobs. Preparation is everything: all the old sealant out, and a clean, dry joint. We can always put it right if it fails.
How do I get a quote for new build mastic in Sullom?
The cost depends on the size of the job, access and how much old sealant has to come out. Ask us for a quote.
When is the best time to reseal in a new build?
That depends on the joint. Failed seals in wet areas need doing now, but cosmetic gaps can wait for movement to slow.
Do you work for developers?
Yes. Second-fix sealing in bathrooms, kitchens, frames and floors is part of what we do. Good preparation keeps snagging to a minimum.
