About our new build mastic in Pencaitland
We work in new homes and on new-build sites across Pencaitland. Whether it’s one en suite or a run of plots, the method is the same: remove, clean, prime where needed, then a neat new bead. Common call-outs are for gaps behind new kitchen upstands and sealant work across a run of new homes, on bathrooms & en suites, kitchens and plot handovers.
Many newer homes in Scotland are timber-framed and settle as they dry out, which shows as gaps at skirtings and floor joints. In older homes, timber floors move through the year too.
The work is covered for a year after we finish. If there’s a problem with it, please send an email to info@mrmastic.co.uk.

How the visit works
There’s no need to move everything out, only the area right around the joints. Everything nearby is protected, and the work takes a few hours in a single home for a typical job. Somewhere like Pencaitland may be a longer drive, and the journey is planned ahead. Mention tracks, gates, ferries or anything else about the route.
- We start by agreeing which joints are on the list, from the snagging sheet or plot schedule.
- Failed or untidy sealant is cut out completely.
- Surfaces are cleaned of building dust and primed where needed.
- We apply a sealant that suits each joint and tool it to a neat finish.
- We check every joint and tell you how long each needs to cure.
Preparing for the visit
- Clear the area around the work
- Tell us about any previous sealing or DIY attempts
- Keep children and pets away from the work area

Related advice
Leave it or put it right?
Water getting past a failed seal in a new build reaches walls and floors that are still settling. Resealing promptly protects the new finishes around it. In a place like Pencaitland, small leaks are easy to put off, but water behind a failed seal does the most damage when nobody’s watching.
Commercial jobs are quoted on the same basis as homes: the amount of work, how we reach it and what it needs, along with when we can work on site. Call for a quick quote and we will explain what it covers.

What affects the cost of new build mastic
We quote each job individually. This is what makes a difference:
- How much old sealant there is and how hard it is to remove
- How many rooms, windows or areas are involved
- Mould in or behind the old joints
- The type of sealant required
The cost reflects the work involved, not a rough estimate. That is why we ask a few questions first.
Asking for a quote
To help us quote quickly, let us know:
- Where the job is, and your postcode
- What the problem is, such as mould, gaps, leaks or cracking
- Access, such as stairs, a lift or height
- If it’s domestic, commercial or a hotel
A good description makes for an accurate quote. Let us know the location, the problem and roughly how many joints, and email photos if that is easy.

Your questions about new build mastic in Pencaitland
Can you help a landlord with a rental near Prestonpans station?
Yes, we work for landlords and letting agents. You can drop us a line at info@mrmastic.co.uk with the address and a few details, and we will give you a fixed price before we start.
Can you do new build mastic in Pencaitland?
Yes. We work across all of Scotland, and Pencaitland is part of that. Just drop us a line at info@mrmastic.co.uk with a few details of the job, and we will send you a clear quote.
Do I need to be at home?
Access is agreed with you when the job is booked. Indoors, that generally means someone at home.
Do you work for developers?
Yes. Second-fix sealing in bathrooms, kitchens, frames and floors is part of what we do. We clean and prime joints properly to keep callbacks down.
Which products do you use?
Quality sealants from brands including Arbo and Everbuild, chosen to suit the joint. We explain the product when we quote.
Will the old sealant be removed?
Yes, always, and completely. New sealant won’t bond properly to old, so any old material comes out before anything new goes in.
Can you reseal over the builder’s sealant?
No. We always remove the existing bead, then clean and prime the joint, before resealing.
Do you work for hotels and businesses?
Yes. Larger jobs can be planned room by room or area by area to suit the site.
DIY sealant or a professional job?
The biggest DIY mistake is sealing over old sealant. New silicone won’t bond to old, so it peels away and traps moisture behind it. All the old material has to come out first.
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is.
Looking after it afterwards
Joint life depends on how it’s used and looked after. We suggest:
- Put sealant faults on your snagging list early
- Don’t wait for the house to settle if water is getting through
- Follow the cure time we give you
- Clean sealant with mild detergent, not abrasives
Leave the sealant for the cure time we give you before showering or bathing. Silicone is normally left for about a day to cure enough for use.
A seal that splits early is often a sign of movement. Getting it resealed properly, and any movement checked, stops it recurring.
