New build mastic in Holy Corner: local notes
Holy Corner 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. 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 Haymarket station, the sealant around baths, showers and frames is worth checking in the first year or two.

About our new build mastic in Holy Corner
Snagging sealant properly means taking the failed bead out completely. Fresh silicone can’t bond to the old layer, so the joint is cut out, cleaned, dried and resealed. If you have gaps opening as the house dries out and settles and plot mastic for developers ahead of handover, we can put it right, on show homes, bathrooms & en suites and skirting & floors alike.
In older Scottish city flats, floors are often timber over joists, with skirting joints that open and close with the seasons. In Holy Corner, a flexible sealant suits those joints better than filler.
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.

Keeping the joints in good condition
After the cure time, these simple habits help:
- Keep water off fresh sealant until it has cured
- Ventilate bathrooms well, especially in the first year
- Record problems with dated photos
- Watch for new gaps as the house dries out
Keep photos of the joints and any snagging correspondence with your builder. It’s useful if you need to raise other issues later.
Do not let the snagging period run out with sealant problems unreported. After that, putting it right may fall to you.
What the job involves on each surface
Show homes
We can refresh show-home sealant that has discoloured or been knocked. We cut it out and reseal neatly.
Windows and doors
Internal joints between frames and plaster often crack as a new house dries. We cut out the cracked bead and reseal with a flexible sealant in a matching colour.
Questions from Holy Corner
What guarantee comes with new build mastic in Holy Corner?
Every job comes with our 12-month guarantee, wherever it is. We’re also fully insured and ARBOMaster approved.
Can you do new build mastic in Holy Corner?
Yes. Our work covers the whole of Scotland, and Holy Corner is part of that. Just drop us a line at info@mrmastic.co.uk with a few details of the job.
How long will you be here?
Typically it takes anything from a few hours to several days, depending on the number of plots. Larger jobs naturally take longer.
Where is Mr Mastic based?
We are based in Crawley, West Sussex, and we cover South East England, London and all of Scotland.
Do you work for letting agents?
Yes, often. Several properties can be quoted together, and between tenancies is a good time for the work.
Why has my new-build shower seal failed already?
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.
How long before the joint can be used?
Many sealants skin over quickly but take longer to cure fully. We’ll give you the cure time for the product we used before we leave.
What sealant do you use?
Each joint gets the product that suits it. Where it moves, gets wet or faces the weather makes a difference, and we will explain our choice.
How it works
Our applicators work methodically: protection first, then preparation, sealing and a tidy-up. Typically it takes a few hours for most snagging lists, longer for a run of plots, and the area is left clean. For a tenement in Holy Corner, work inside your flat is between us and you, while shared parts may need the factor or neighbours to agree. Tell us which applies when you book.
- We look at why each joint failed, including any movement.
- Old sealant is cut out and the joints cleaned.
- Joints are dried and primed where the product calls for it.
- Baths are filled with water, then the new sealant is applied.
- We check every joint and leave you with the cure times.
Preparing for the visit
- Mention any parking rules near the property
- Let us know if you’ve seen damp or leaks
- Move anything stored near the joints
How to get a quote
Asking for a quote is easy: let us know the job and the location, and roughly how big it is. Photos by email help us understand the job, and we’ll take it from there.

Signs you need new build mastic in Holy Corner
When the heating goes on in the first winter, the house dries fast. Skirting, frames and worktops pull away slightly and cracks appear in the sealant.
People normally contact us when they notice something like this:
- Worktop and upstand sealant coming away
- Internal frame sealant that has split
- Joints pulling apart as timber shrinks
- Plot mastic for developers ahead of handover
In and around Holy Corner, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.

Why deal with it now?
A failed shower or bath seal in a new home lets water into floors and walls that are still drying out. Dealing with it early keeps the damage away from ceilings, floors and finishes. Private landlords in Holy Corner must meet the Repairing Standard, and damp or leaks can fall short of it, so failed sealant is best replaced before it becomes a complaint.
Doing several joints on one visit is generally more efficient than separate visits, so tell us about everything that needs sealing. You will get one clear quote for the whole job.
