About our new build mastic in Prestwick
Developers send us the plot schedule and we work through it. Bathrooms, en suites, kitchens, frames and skirting are sealed ready for handover. Common call-outs are for untidy sealant flagged on a snagging list and gaps opening as the house dries out and settles, on skirting & floors, kitchens and plot handovers.
Commercial units and shops in a town like Prestwick have floors with joints that need resealing as they wear. Resealing them early stops the edges breaking away.
You get a one-year guarantee, the same in Prestwick as everywhere else we work.

Surface by surface
Bathrooms and en suites
En suite seals are easy to miss on a snagging list until they leak. A proper reseal keeps water in the tray.
Windows and doors
Draughts around new frames are often a sealant gap. We look at the joints and reseal where needed.

What else we do in Prestwick
Can I do it myself?
A DIY attempt does not rule out a professional job. We remove it and do the joint properly, so just mention it when you contact us.
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
How it works
There’s no need to move everything out before we come, only the area right around the joints. Everything nearby is protected, and the job takes anything from a few hours to several days, depending on the number of plots in most cases. Parking around Prestwick is rarely difficult, though older streets in the centre can be tight. If you’re in a flat with a shared stair or a door entry system, let us know when you book.
- We look at why each joint failed, including any movement.
- We remove the failed sealant and clean the joints.
- Joints are dried and primed where the product calls for it.
- Baths are filled with water, then the new sealant is applied.
- The finished joints are checked and the cure times given.
Getting ready for the visit
- Tell us about access, such as stairs, a lift or high-level joints
- Tell us if parking is tricky
- Try not to wet indoor joints just before the visit

Aftercare tips
Looking after new joints is easy:
- Watch for new gaps as the house dries out
- Wait for the cure time before using a resealed shower
- Record problems with dated pictures
- Report sealant problems to your builder during the snagging period
Clean the sealant with a mild detergent and a soft cloth. Avoid abrasive pads and strong solvents.
Lifting sealant traps moisture and mould behind it. Resealing before mould gets in keeps the job straightforward.
What we are called out for in Prestwick
Later trades and the final clean can damage fresh sealant. A bead disturbed before it has cured may never seal properly and it shows once the home is in use.
These are the problems we’re asked about most:
- Frame joints opening as the plaster dries
- Skirting joints opening in the first winter
- Gaps opening as the house dries out and settles
- Plot mastic for developers ahead of handover
Around Prestwick, as everywhere, new build mastic is only as good as the preparation behind it.
Questions to ask before you book
- When the joint can take water or movement
- The length of the guarantee
- Are they insured?
- Is VAT in the price?
When it isn’t the sealant
Before you book, it’s worth knowing the limits:
- Settlement cracks that need a surveyor
- Leaking fittings rather than failed sealant
- A tray or bath that is not properly supported, until it’s fixed
If in doubt, email us at info@mrmastic.co.uk and we’ll say what we think before booking.

What new build mastic looks like in Prestwick
Prestwick is close to the coast. Plot mastic on new homes near the coast takes more weather than it would inland, so any gaps are best picked up early. The west of Scotland is wetter than the east, which means plot mastic and the sealant in new homes has to cope with a lot of rain.
If you’ve bought a new home near Prestwick Town station, the sealant around baths, showers and frames is worth checking in the first year or two.

Do I have to be there?

What do you need from me for a quote?
Only a few details: where it is, what you’ve noticed and how we reach it. Then drop us a line at info@mrmastic.co.uk.
Is there a guarantee?
Yes: twelve months. If there’s a problem with our work in that time, tell us and we’ll put it right.
Do the sealants smell?
Possibly a little. It fades as the sealant cures, and ventilation helps.
Is it worth resealing while the house is still settling?
It depends on whether water is getting through. A leaking shower or bath seal should be redone straight away, but cosmetic gaps can wait for movement to slow.
Who should fix failed sealant in a new build?
Report it to the builder first while you are covered. Once that is done, or if they won’t put it right, we will cut it out and reseal it.
