New build mastic for homes and businesses in Haddington
A new house keeps drying out and settling for its first couple of years. Timber dries and shrinks, and baths and trays settle, and sealant applied in a hurry at handover can split. If you’re dealing with kitchen sealant that has pulled off the wall and gaps opening as the house dries out and settles, we can put it right.
A lot of new homes in Scotland are timber-framed, and they settle in their first years, so skirting and floor joints can open up in the first year or two.
Whatever the size of the job, it’s backed by our 12-month guarantee in Haddington and across East Lothian.

Keeping the joints in good condition
Aftercare is simple, and it makes a real difference:
- Clean sealant with mild detergent, not abrasives
- Act quickly if a seal starts to leak
- Ventilate bathrooms well, especially in the first year
- Report sealant problems to your builder during the snagging period
Ventilation matters in a new home, which is still drying out. Use the extractor fan or open a window after showers to help keep mould away.
A failed seal in a new home lets water into joists, plasterboard and ceilings. Catching it early keeps the fix to the sealant and protects the rest of the house.
Joints and finishes in Haddington homes
Timber frame is common in newer Scottish homes, and as the frame dries and settles, skirting and sealant joints can open up.
If you’ve bought a new home near Drem station, the sealant around baths, showers and frames is worth checking in the first year or two.

What we’re called out for in Haddington
If plaster or screed was still damp when it was sealed, the bond suffers. Site programmes don’t always leave time for joints to dry before the sealant goes on.
Signs it’s time to call us include:
- Shower seals failing in the first year or two
- Cracked sealant around new window and door frames
- Cracks appearing as a new home settles
- Beads laid onto grit and dust from the build
In and around Haddington, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.

The process
Every visit runs the same way: we check the joints, protect the area around them, carry out the job and tidy away. It generally takes a few hours for most snagging lists, longer for a run of plots. Parking around Haddington is rarely difficult, though older streets in the centre can be tight. For flats, mention the shared stair or door entry system.
- First we work through your snagging list or plot schedule with you.
- We cut out every bit of the failed or messy sealant.
- Surfaces are cleaned of building dust and primed where needed.
- New sealant suited to each joint is applied and tooled neatly.
- Finally, each room is checked and you are given the cure time.

Advice
Haddington: your questions answered
I let a flat near Drem station. Can you help?
Yes, we work for landlords and letting agents. You can email us at info@mrmastic.co.uk with the address and a few details, and we will give you a fixed price before work begins.
Can you do new build mastic in Haddington?
Yes, Haddington is within the area we cover. We work across all of Scotland. You can send an email to info@mrmastic.co.uk and let us know what needs doing, and we will send you a clear quote.
Do you do commercial work?
Yes, regularly. We can plan bigger jobs in stages to suit the site.
Can you do several jobs on one visit?
Yes. Several rooms, windows or areas can go on one quote.
Which products do you use?
Quality sealants from brands including Arbo and Everbuild, picked for each joint. We’ll tell you what we’re using and why.
Is it worth resealing while the house is still settling?
Any seal that’s leaking should be redone straight away. Cosmetic gaps can wait until the first year or two of movement has passed.
Do you take out the old sealant first?
Yes, every time. New sealant will not bond properly to old, so any old material comes out before anything new goes in.
How long does new build mastic take?
A typical job takes anything from a few hours to several days, depending on the number of plots. Your quote will say how long we expect yours to take.
Other services in Haddington
What the job involves on each surface
Bathrooms and en suites
Trays and baths in new builds settle as they’re used. The joint is stripped back before the new bead goes in and baths are filled before sealing.
Windows and doors
External mastic around new windows and doors is sometimes rushed or missed. It’s resealed with an exterior sealant suited to the frame and wall.
Can I do it myself?
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
Why it’s worth doing now in Haddington
Water getting past a failed seal in a new build reaches walls and floors that are still settling. Dealing with it early keeps the damage away from ceilings, floors and finishes. In flats with a shared stair in Haddington, a leak from a failed seal can affect the flat below too, which turns a small job into a bigger one.
Rather than a set price list, we look at what your job involves: the amount of work, the old material and the access. You will know the price before we begin.
