New build mastic for homes and businesses in Gulberwick
In a new home, every joint should have a clean, even bead. When the finish is smeared, patchy or already cracking, it’s worth putting right early, before water reaches anything behind it. Common call-outs are for cracked caulk along new skirting and cracks appearing as a new home settles, across show homes, bathrooms & en suites and skirting & floors.
Work in a place like Gulberwick is planned ahead, journey included. Outdoor plot mastic needs dry weather, but indoor floor and skirting joints can be sealed whatever the forecast.
There’s a 12-month guarantee on every job, large or small.

Joints and finishes in Gulberwick homes
Gulberwick is close to the coast. Plot mastic on new homes near the coast takes more weather than it would inland, so any gaps are best picked up early. Timber frame is common in newer Scottish homes, so skirting and sealant joints can open up as the building settles.
Whether the job is in Gulberwick itself or nearby, the right material for each joint matters as much as a neat finish.

Should I try it myself first?
The biggest DIY mistake is sealing over old sealant. New silicone will not bond to old, so it lifts and traps water and mould underneath. All the old material has to come out first.
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.

Signs you need new build mastic in Gulberwick
Baths and trays settle under load once the home is lived in. A bath sealed empty drops slightly when filled, straining the joint and the sealant may split.
Most people get in touch when they notice one of these:
- Messy sealant that spoils new finishes
- Frame joints opening as the plaster dries
- Gaps behind new kitchen upstands
- New-build shower sealant that has already split
Around Gulberwick, as everywhere, new build mastic is only as good as the preparation behind it.

What the job involves on each surface

Bathrooms and en suites
Trays and baths in new builds settle as they’re used. We reseal once the old bead is fully out.
How we quote for new build mastic
Jobs vary more than people expect. What affects the quote:
- The old material and how stubborn it is
- Whether there’s mould to deal with
- The number and length of the joints
- Access and height
The cost reflects the work involved, not a rough estimate. That’s why we ask about the job first and agree the price before starting.
What we need to know
Photos by email are helpful but not essential. Please mention:
- What’s wrong with the joints now
- Where the job is, and your postcode
- If someone has resealed it before
- Access, such as stairs, a lift or height
Getting a quote is simple: let us know what needs doing and where. Photos by email help us understand the job, and we’ll take it from there.
What happens on the day
Good joint work is mostly preparation, so that is where we spend the time. Every joint is cleaned and dried before new material goes in. All told, the work takes a few hours for most snagging lists, longer for a run of plots. For a place like Gulberwick, longer drives are planned in advance. Tell us about tracks, gates, a ferry crossing or anything unusual about getting there.
- First we work through your snagging list or plot schedule with you.
- We cut out every bit of the failed or messy sealant.
- Each joint is cleaned of dust and grit, then primed if required.
- New sealant suited to each joint is applied and tooled neatly.
- We check every joint and tell you how long each needs to cure.
Preparing for the visit
- Where the joints are inside, avoid wetting them before we arrive
- Let us know about stairs, lifts or work at height
- Keep pets and children clear of the area while we work

Advice
Common questions in Gulberwick
Do you cover smaller places like Gulberwick?
Yes, smaller places are covered as well as towns. We work across all of Scotland, including the islands, where work is planned around ferry crossings. Just mention lanes, gates or anything else about the route when you book.
What guarantee comes with new build mastic in Gulberwick?
All our work, in Gulberwick and everywhere else, comes with a 12-month guarantee. We’re fully insured, and an ARBOMaster approved applicator.
I’m a tenant. Can you help?
Yes. Check with your landlord; we can send the quote to them too.
Do I have to be there?
It depends on the job. Inside work needs someone to give us access, and for outside work we’ll agree access with you when we book.
Are you fully insured?
Yes. We are fully insured, and we can confirm the details when we quote.
Is it messy?
No. We protect the surfaces around the joints, and we clear up the old sealant and our materials before we leave.
Can you do several jobs on one visit?
Yes, and it often makes sense. Doing several areas at once is normally more efficient.
Do you use white or clear sealant?
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 work begins.
Why it’s worth doing now in Gulberwick
A quick bead over the top of the old sealant can look fine at first, but it will not bond to the old layer. Taking it all out and starting again is the only way to get a lasting seal. 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.
Homes and businesses are quoted the same way: the amount of work, how we reach it and what it needs, plus any working-time requirements on site. Call for a quick quote and we’ll go through it with you.
