New build mastic for homes and businesses in Ardheisker
A new house keeps drying out and settling for its first couple of years. Timber dries and shrinks, and baths and trays settle, so sealant that was laid quickly before handover often cracks. We work on windows & doors, plot handovers and kitchens, and people most often call us about sealant applied over dusty or wet surfaces and cracked caulk along new skirting.
Work in a place like Ardheisker is planned ahead, journey included. Outdoor plot mastic needs dry weather, but indoor floor and skirting joints can be sealed whatever the forecast.
Our work is backed for twelve months.

Work for landlords, hotels and businesses
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.
We also work for businesses, from offices to washrooms and kitchens. For commercial premises, we can talk through working times when we quote.
Joints and finishes in Ardheisker homes
Ardheisker is close to the coast. New homes near the sea put their outside mastic to work from day one, so any gaps are best picked up early. Island jobs need planning around ferries and the weather, so give us as much notice as you can.
Around Ardheisker, as everywhere, new build mastic is only as good as the preparation behind it.

Common questions in Ardheisker
Is Ardheisker within the area you cover?
Yes, smaller places are covered as well as towns. Our work covers the whole 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.
Is there a guarantee on new build mastic in Ardheisker?
Every job comes with our 12-month guarantee, wherever it is. We’re also fully insured and ARBOMaster approved.
Can you do plot mastic on a new development?
Yes. We seal plots to the developer’s programme. Tell us the plots and the joints involved for a clear quote.
Do you take out the old sealant first?
Yes, every time. New sealant won’t bond properly to old, so any old material comes out before anything new goes in.
Do the sealants smell?
It depends on the product. Some products have a noticeable smell, others very little.
Where is Mr Mastic based?
Our base is in Crawley, and we cover South East England, London and all of Scotland.
Who should fix failed sealant in a new build?
Start with the builder if you’re in the snagging or warranty period. If it isn’t resolved, we’ll cut it out and reseal it.
What does new build mastic cost?
We do not publish prices, because the cost depends on the job: its size, the old material, access and the product needed. We agree the price before any work begins.
Common problems we fix in Ardheisker
Sealant applied onto damp surfaces does not bond well. On a busy site, joints aren’t always given time to dry.
Most people get in touch when they notice one of these:
- Shower seals failing in the first year or two
- Messy sealant that spoils new finishes
- Joints pulling apart as timber shrinks
- Frame joints opening as the plaster dries
For jobs in and around Ardheisker, choosing the right material for each joint is as important as a tidy finish.

How it works
When we arrive, we start by going over the job with you, so you know exactly what we are doing. Surfaces next to the work are protected before any work begins. The work generally takes a few hours for most snagging lists, longer for a run of plots. Around Ardheisker, 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 we start.
- 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.
- The finished joints are checked and the cure times given.
Preparing for the visit
- Clear items away from the joints we are working on
- Tell us if parking is tricky
- Tell us about access, such as stairs, a lift or high-level joints

Related advice
DIY sealant or a professional job?
A DIY attempt does not rule out a professional job. We cut it out and start again, so just mention it when you contact us.
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
Why it’s worth doing now in Ardheisker
If you’re still in the builder’s snagging or warranty period, ask them to put it right first. If it keeps failing or is not dealt with, we can reseal it properly. In a place like Ardheisker, small leaks are easy to put off, but water through a failed joint keeps working away until it’s fixed.
Some things make a job bigger or smaller: how much old sealant there is and how stubborn it is, whether mould needs treating, and whether the work is at height. We take all of that into account in your quote.
