New build mastic in Millerhill, done properly
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 have internal frame sealant that has split and leaking shower tray seals in a new home, we can put it right, whatever the surface.
New homes in smaller Scottish places are often single plots, self-builds or small developments. They need their sealant and floor joints finished just as carefully as on a big site.

New build mastic around Millerhill
Millerhill is close to the coast. Plot mastic on new homes near the coast takes more weather than it would inland, so it’s worth checking at snagging. Many new homes in Scotland are timber-framed, and as the frame dries and settles, skirting and sealant joints can open up.
If you’ve bought a new home near Shawfair station, the sealant around baths, showers and frames is worth checking in the first year or two.
Millerhill is about 2 miles north-west of Dalkeith, in Midlothian. From the centre of Millerhill to the outskirts, we cover new build mastic for every kind of property. Our Midlothian coverage runs to 33 places, Millerhill among them.
We cover every part of the EH22 postcode area for new build mastic and the streets around it. If you need new build mastic at a property on Wymet Grove, Wymet Gardens and Cocklerow Loan or a nearby road, we can help. We also cover Newton Village (1 mile west), Shawfair (1 mile north-west), Old Craighall (1 mile north-east), Newcraighall (2 miles north) and Whitecraig (2 miles east). Larger places within reach include Bonnyrigg (3 miles south), Penicuik (8 miles south-west), Loanhead (4 miles south-west), Gorebridge (5 miles south), Newtongrange (3 miles south) and Mayfield (3 miles south-east).
Landmarks near Millerhill
We work in homes and buildings around Drum Park and the streets around them. Millerhill has its own railway station: Shawfair station.

What happens on the day
We work through the job in order: protect, prepare, seal, tidy. Typically it takes a few hours for most snagging lists, longer for a run of plots and we leave things clean and tidy. Outside jobs in Millerhill need a dry day, because sealant will not bond to a wet joint, so external jobs may need to move if the day turns wet. Indoor work goes ahead whatever the weather.
- First we work through your snagging list or plot schedule with you.
- The old bead comes out in full, with no layer left behind.
- We clean off dust from the build and prime the surfaces where the product needs it.
- A sealant chosen for each area goes in and is tooled smooth.
- Each area is checked and left with its cure time.
Preparing for the visit
- Let us know if you’ve seen damp or leaks
- For business premises, tell us about site rules or sign-in
- Tell us about any previous sealing or DIY attempts

Advice
DIY sealant or a professional job?
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
If you’ve already had a go yourself, that is fine. We cut it out and start again, so tell us about it when you ask for a quote.
Aftercare tips
Once the sealant has cured, a few habits help it last:
- Keep water off fresh sealant until it has cured
- Raise failed sealant with the developer while you are covered
- Clean sealant with mild detergent, not abrasives
- Record problems with dated pictures
Ventilation matters in a new home, which is still drying out. Run the fan or open a window after bathing.
Leave a failed new-build seal and water can reach the floor and the ceiling below. Early resealing keeps the job small and the new finishes intact.
What the job involves on each surface
Skirting and floors
New homes often develop a gap between skirting and floor. We seal it with a flexible sealant that copes with the movement.
Bathrooms and en suites
En suite showers are a common source of leaks into the room below. A proper reseal keeps water in the tray.
What we’re called out for in Millerhill
The wrong product is sometimes used in the wrong place: decorators’ caulk in a wet area, or a stiff sealant where there’s movement. Neither lasts long.
Most people get in touch after spotting one of these:
- Worktop and upstand sealant coming away
- Internal frame sealant that has split
- Joints pulling apart as timber shrinks
- Second-fix sealing on new plots
In and around Millerhill, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.

Questions from Millerhill
I let a flat near Shawfair station. Can you help?
Yes, landlords and agents are among the people we work for. Just drop us a line at info@mrmastic.co.uk with the address and what needs doing, and we’ll send you a clear quote.
Is Millerhill within the area you cover?
Yes, we do. Our work covers the whole of Scotland, from towns to the smallest places. Longer journeys are simply planned in advance.
Is it normal for sealant to crack in a new home?
A new house dries and settles for a year or two, and sealant is often rushed onto dusty, unprimed surfaces. Both lead to early failure.
Are you insured?
Yes. We are fully insured.
Will you leave a mess?
Not at all. We work neatly, protect the area around the joints and tidy up afterwards.
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.
Do you take on second-fix sealing for builders?
Yes. We work through plots to your schedule, room by room. Tell us the plots and the joints involved for a clear quote.
When is the sealant fully cured?
Different products cure at different speeds, so follow the cure time we give you.
