- Gaps opening as the house dries out and settles
Different surfaces, different methods
Windows and doors
External mastic around new windows and doors is sometimes rushed or missed. We reseal it with a weatherproof, flexible sealant.
Show homes
We seal show-home bathrooms, kitchens and frames. We’ll plan around viewing times.
New build mastic for homes and businesses in Hamister
Snagging sealant properly means taking the failed bead out completely. New silicone will not bond to old silicone, so the joint is cut out, cleaned, dried and resealed. If you have cracked sealant around new window and door frames and kitchen sealant that has pulled off the wall, we can help, on show homes, windows & doors and kitchens alike.
New homes in smaller Scottish places are often single plots, self-builds or small developments. Each needs its sealant and floor joints finished as carefully as on a big site.
A one-year guarantee comes with the work, just as it does everywhere we cover.

Why it’s worth doing now in Hamister
A hairline gap at a skirting can wait, but a leaking seal cannot. If you’re unsure which you have, drop us a line at info@mrmastic.co.uk with photos. Out of town in Scotland, exposed walls take a lot of weather, and damp in stone or harled walls takes a long time to dry once water gets behind a joint.
The cost depends on the size of the job, how much old material has to come out and access to the work. You’ll have a clear quote before any work starts, so you know where you stand.

Should I try it myself first?
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and doesn’t move well, and getting the depth right matters as much as the look.
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
What affects the quote in Hamister
There’s no set price list, because jobs vary so much. The quote depends on:
- How many rooms, windows or areas are involved
- When we can work, for business premises
- Which sealant suits the joint
- The amount of work
Some things make a job bigger or smaller: the old material and how easily it comes out, whether mould needs treating, and whether we need extra access for height. Your quote takes all of that into account.
Asking for a quote
When you contact us, it’s useful to know:
- Whether it has been sealed before
- Pictures of the joints, sent by email
- Whether it’s a home or a business
- How many joints, rooms or windows are involved

FAQs for Hamister
Is new build mastic in Hamister guaranteed?
Every job comes with our one-year guarantee, wherever it is. We are also fully insured and ARBOMaster approved.
Do you cover smaller places like Hamister?
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. Let us know about access, parking and anything unusual about getting there when you book.
Should I wait before resealing?
For failed seals that let water through, the best time is now. For small cosmetic gaps, waiting until the house has settled can save doing them twice.
Will the old sealant be removed?
Yes. All of the old material is cut out and the joint cleaned before applying anything new.
Do you use white or clear sealant?
The colour is chosen to suit the tiles, worktop or frame. Tell us what you’d like when you get a quote.
Can I add another job to the visit?
Yes. Several rooms, windows or areas can go on one quote.
Can I do it myself?
You can, for simple jobs. The key is preparation: remove all the old material and work on a clean, dry joint. If it does not work out, we can redo it.
My new home is still under warranty. Should I contact you?
Start with the builder if you are in the snagging or warranty period. Once that’s done, or if they will not put it right, we’ll cut it out and reseal it.

Common problems we fix in Hamister
New homes are full of moisture from plaster, screed and concrete, which takes a year or two to dry out. Drying timber shrinks and pulls joints apart and the sealant has to cope with the movement.
These are the problems we are asked about most:
- Joints pulling apart as timber shrinks
- Internal frame sealant that has split
- Plot mastic for developers ahead of handover
- Untidy sealant flagged on a snagging list
Whether the job is in Hamister itself or nearby, the right material for each joint matters as much as a neat finish.

For landlords and businesses
If you manage several properties in or around Hamister, jobs at different addresses can be quoted together. Send us the addresses and the work at each.
A neglected joint can let water reach the structure, which is a bigger problem in a rented property. Resealing at the right time is simple maintenance.
The process
We bring everything the job needs with us, so there’s nothing for you to buy. Once we have agreed what’s being done, we protect the area and start. It normally takes a few hours for most snagging lists, longer for a run of plots. Around Hamister, distance and access matter more than parking. Tell us how to find the property and how to reach the work.
- We start by going through the snagging items or plot schedule with you.
- Every bit of the old builder’s sealant is cut out.
- We clean out the dust and grit left from the build.
- Primer goes on where the surface and product need it, then the new sealant.
- We tool every joint neatly and tell you when each area can be used.
Getting ready for the visit
- Keep pets and children clear of the area while we work
- Tell us if parking is tricky
- Mention if the joints have been sealed before
