About our new build mastic in Kilmarnock
In a new home, every joint should have a clean, even bead. Smeared, patchy or cracked sealant is worth sorting early, before water reaches anything behind it. If you have internal frame sealant that has split and gaps between new skirting and floors, we can help.
Around Kilmarnock, shops and business units have floor joints that break down under traffic. Resealing them early stops the edges breaking away.
We guarantee the work for a year. If there’s a problem with our work within the year, let us know and we will sort it.

Aftercare tips
To keep the joints looking good and working properly:
- Get a leaking seal dealt with right away
- Watch for new gaps as the house dries out
- Record problems with dated photos
- Follow the cure time we give you
Clean the sealant with a mild detergent and a soft cloth. Avoid abrasive pads and strong solvents.
Mould takes hold quickly in sealant that has gaps or lifted edges. Resealing before mould gets in keeps the job straightforward.

Signs you need new build mastic in Kilmarnock
Fresh sealant can be knocked or cut by trades finishing off. If it’s disturbed before curing, the joint can be left weak and it shows once the home is in use.
These are the problems we’re asked about most:
- Joints pulling apart as timber shrinks
- Untidy sealant flagged on a snagging list
- Skirting joints opening in the first winter
- New-build shower sealant that has already split
In and around Kilmarnock, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.

Can I do it myself?
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions, then guaranteed for a year.
Sealing over old silicone is the commonest DIY error. 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.
New build mastic around Kilmarnock
Timber frame is common in newer Scottish homes, so skirting and sealant joints can open up as the building settles. 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 Kilmarnock station, the sealant around baths, showers and frames is worth checking in the first year or two.

Kilmarnock: your questions answered
Can you help a landlord with a rental near Kilmarnock station?

Is new build mastic in Kilmarnock guaranteed?
Every job comes with our one-year guarantee, wherever it is. We’re also fully insured and ARBOMaster approved.
Do you use white or clear sealant?
We use white, clear or a colour to suit the finishes. Let us know your preference when you ask for a quote.
Can you quote for more than one area?
Yes, and it often makes sense. Combining jobs makes good use of the visit, so mention them when you ask for a quote.
What do you put in the joint?
It depends on the joint: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. We use products from Arbo and Everbuild.
Is it normal for sealant to crack in a new home?
It’s common, and there are usually two reasons: movement as the house dries and settles, and sealant laid onto dust without primer. A proper reseal deals with both.
Will the old sealant be removed?
Yes. Sealing over old sealant is the main reason resealing fails early, so we never do it.
Are you insured?
Yes, we’re fully insured.
Different surfaces, different methods
Show homes
We can refresh show-home sealant that has discoloured or been knocked. The old bead comes out and a clean new one goes in.
Bathrooms and en suites
New-build bathrooms and en suites are where sealant fails most often. The old sealant comes out and anti-fungal sanitary silicone goes in after cleaning and priming.
