Common problems we fix in Garthamlock
A new house holds a lot of water from the build, and it dries out over the first couple of years. As it does, timber shrinks and joints open and the sealant has to cope with the movement.
These are the problems we are asked about most:
- New-build shower sealant that has already split
- Gaps between new skirting and floors
- Worktop and upstand sealant coming away
- Gaps opening as the house dries out and settles
Around Garthamlock, as everywhere, new build mastic is only as good as the preparation behind it.
What your quote should include
- The length of the guarantee
- Whether the sealant suits the joint
- Is the old sealant removed completely?
- Who does the work, and how experienced they are
New build mastic in Garthamlock, done properly
New homes move as they dry out. Timber shrinks, plaster dries and baths and trays bed down, so sealant that was laid quickly before handover often cracks. We’re often asked to deal with internal frame sealant that has split and sealant applied over dusty or wet surfaces, across skirting & floors, show homes and bathrooms & en suites.
Work in a place like Garthamlock is planned ahead, journey included. Outdoor plot mastic needs dry weather, but indoor floor and skirting joints can be sealed whatever the forecast.
Whatever the size of the job, you get the same 12-month guarantee.

How it works
We work through the job in order: protect, prepare, seal, tidy. Typically it takes anything from a few hours to several days, depending on the number of plots, and the area is left clean. In smaller Scottish places, parking is normally less of an issue than access and distance. Tell us how to find the property and how to reach the work.
- We look at why each joint failed, including any movement.
- Old sealant is cut out and the joints cleaned.
- Joints are dried and primed where the product calls for it.
- New sealant goes in, with baths filled first so they’re at their heaviest.
- We check every joint and leave you with the cure times.
How to prepare
- Mention if the joints have been sealed before
- For indoor joints, keep the area dry beforehand if you can
- Mention any sign-in or site rules at work premises

Advice
Your questions about new build mastic in Garthamlock
Do you work for landlords with property near Stepps station?
Yes, we work for landlords and agents. Just email us at info@mrmastic.co.uk and tell us about the property, and we’ll give you a clear price.
Can you do new build mastic in Garthamlock?
Yes, Garthamlock is within the area we cover. We work across all of Scotland. You can send an email to info@mrmastic.co.uk and tell us what needs doing.
Which products do you use?
Each joint gets the product that suits it. Movement, water and weather all affect the choice.
Is it worth resealing while the house is still settling?
For failed seals that let water through, the best time is now. Cosmetic gaps can wait until the first year or two of movement has passed.
Can you quote for more than one area?
Of course. Doing several areas at once is normally more efficient.
Where do you work from?
We are a Crawley-based firm. We work across South East England, London and Scotland.
Can you work on commercial sites?
Yes, regularly. We can plan bigger jobs in stages to suit the site.
Will the old sealant be removed?
Yes, every time. New sealant will not bond properly to old, so the joint is cleaned back first.
When something else is needed
We’ll always be straight with you, so here’s what sealant can’t fix:
- Settlement cracks that need a surveyor
- Your warranty claim itself, which is between you and the builder
- Plumbing faults behind the sealant
Not sure which it is? You can drop us a line at info@mrmastic.co.uk and we’ll tell you honestly before booking.

Landlords, agents and businesses in Garthamlock
A neglected joint can let water reach the structure, which is a bigger problem in a rented property. Keeping joints in good order is simple maintenance that we can handle for you.
Housing providers, facilities teams and property managers book us too. We can quote a run of properties together, and we are fully insured.
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.
Plot handovers
Plot mastic is carried out to the developer’s schedule. Joints are prepared properly before sealing so the sealant lasts.
DIY sealant or a professional job?
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is.
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.

New build mastic around Garthamlock
Timber frame is common in newer Scottish homes, and as the frame dries and settles, skirting and sealant joints can open up. The west of Scotland is wetter than the east, so there’s plenty of rain for plot mastic and the sealant in new homes to keep out.
If you’ve bought a new home near Stepps station, the sealant around baths, showers and frames is worth checking in the first year or two.
