Penninghame New Build Mastic
Problem with your new-build sealant joints in Penninghame? We remove the old material, prepare the joints and seal them properly.
- Smeared, uneven beads picked up at snagging
- Gaps opening as the house dries out and settles
- Sealant that never bonded to the surface
New build mastic in Penninghame
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. If you have smeared, uneven beads picked up at snagging and kitchen sealant that has pulled off the wall, we can put it right, on show homes, kitchens and skirting & floors alike.
Timber frame is common in newer Scottish homes, and it settles over the first years, so skirting and floor joints can open up. In older homes, timber floors move through the year too.
We guarantee the work for a year. If there’s a problem with our work within the year, let us know and we’ll sort it.

Should I try it myself first?
If you’re 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.
If you’ve already had a go yourself, that is fine. We cut it out and start again, so just mention it when you contact us.
Penninghame: your questions answered
Is there a guarantee on new build mastic in Penninghame?
Every job comes with our 12-month guarantee, wherever it is. We are fully insured, and an ARBOMaster approved applicator.
Do you cover smaller places like Penninghame?
Yes, smaller places are covered as well as towns. Our work covers the whole of Scotland. Just mention lanes, gates or anything else about the route when you book.
Is there any odour?
That depends on the sealant. Some products have a noticeable smell, others very little.
Is it normal for sealant to crack in a new home?
A new house dries and settles for a year or two, and sealant is often rushed onto dusty, unprimed surfaces. Either can make it fail early.
Do you hold any approvals?
Yes. We’re an ARBOMaster approved applicator, which is run for the Arbo sealant brand.
Is it worth resealing while the house is still settling?
If the seal has failed and water is getting in, do it now. Hairline cosmetic gaps can wait until the house has settled.
How long does the job take?
That depends on the amount of work, but as a guide it takes a few hours for most snagging lists, longer for a run of plots. We’ll tell you when we quote.
Where do you work from?
Our base is in Crawley, and we cover South East England, London and all of Scotland.
Surface by surface
Plot handovers
Taking time over preparation reduces return visits. Dust from the build is removed first and prime where the product needs it.
Skirting and floors
Where the floor meets a bath panel or kitchen plinth, the joint keeps mop water out. We seal them with a sealant suited to wet areas.
How to look after the new joints
Once the sealant has cured, a few habits help it last:
- Ventilate bathrooms well, especially in the first year
- Follow the cure time we give you
- Get a leaking seal dealt with straight away
- Keep photos and emails about snagging items
Keep the bathroom ventilated, especially in the first year. Use the extractor fan or open a window after showers so moisture does not sit on the sealant.
A failed seal in a new home lets water into joists, plasterboard and ceilings. Early resealing keeps the job small and the new finishes intact.
How it works
We work through the job in order: protect, prepare, seal, tidy. For most jobs that takes a few hours in a single home. In smaller Scottish places, parking is usually less of an issue than access and distance. Tell us how to find the property and how to reach the work.
- 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.
- Each joint is cleaned of dust and grit, then primed if required.
- A sealant chosen for each area goes in and is tooled smooth.
- We check every joint and tell you how long each needs to cure.
Before we arrive
- Tell us about access, such as stairs, a lift or high-level joints
- Clear items away from the joints we are working on
- Where the joints are inside, avoid wetting them before we arrive

What affects the quote in Penninghame
Some jobs are bigger than they look, and some smaller. What affects the quote:
- The amount of work
- How many areas need sealing
- Whether there’s mould to deal with
- Which sealant suits the joint
Leaving a failed joint generally makes the job bigger, not smaller, because water and mould keep working on it. If you are not sure whether it needs doing, email us at info@mrmastic.co.uk and we’ll give you an honest view and a quote.
Helping us quote
When you contact us, it’s useful to know:
- How many joints, rooms or windows are involved
- A few pictures by email, if you can
- How we’d reach the joints
- Whether it’s a home or a business
A good description makes for an accurate quote. Tell us where the job is, what’s wrong and how much there is, and email pictures if that’s easy.
