New build mastic in Mount Pleasant, done properly
We work in new homes and on new-build sites across Mount Pleasant. One shower or a whole phase of plots, the method doesn’t change: remove, clean, prime where needed, then a neat new bead. We are often asked to deal with cracked caulk along new skirting and frame joints opening as the plaster dries, on kitchens, plot handovers and show homes.
Somewhere as small as Mount Pleasant, new homes tend to be conversions, self-builds or a few houses rather than an estate. Each still needs its sealant and floor joints finished properly.
We guarantee the work for a year. If there’s a problem with our work within the year, let us know and we’ll sort it.

Looking after it afterwards
Simple care keeps the joints in good condition. Our advice:
- Wait for the cure time before using a resealed shower
- Ventilate bathrooms well, especially in the first year
- Clean sealant with mild detergent, not abrasives
- Do not wait for the house to settle if water is getting through
Keep an eye on the joints over the first couple of years. Hairline gaps can open as timber and plaster dry.
A failed seal in a new home lets water into joists, plasterboard and ceilings. Catching it early keeps the fix to the sealant and the new finishes intact.
FAQs for Mount Pleasant
Can you help a landlord with a rental near Sway station?

Will you come out to Mount Pleasant?
Yes, Mount Pleasant is covered. Our work covers London and the South East, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
Do you have insurance?

What do you need from me for a quote?

Can I do it myself?
It depends on the job. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional.
Do I need to be at home?
For indoor joints, yes, someone needs to let us in. Once we’ve agreed the job, you don’t need to watch us work.
What do you put in the joint?
Each joint gets the product that suits it. Movement, water and weather all affect the choice.
What does new build mastic cost?
There’s no set price, as it depends on the job: its size, the old material, access and the product needed. We agree the price before any work begins.
How the visit works
Most of a good job is in the preparation, so that’s where we spend the time. Joints are cleaned back and dried before anything new goes in. All told, the work takes a few hours for most snagging lists, longer for a run of plots. In a small place like Mount Pleasant, access is generally the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- First, the list of joints is agreed from your snagging sheet or plot schedule.
- Every bit of the old builder’s sealant is cut out, with no layer left behind.
- Joints are vacuumed and cleaned of building dust.
- We prime where needed and apply a sealant suited to each joint.
- Each bead is tooled and the cure times explained.
Preparing for the visit
- Tell us about any previous sealing or DIY attempts
- On commercial sites, let us know about site rules
- Let us know if you’ve seen damp or leaks

What affects the cost of new build mastic

Why act early in Mount Pleasant
The builder is generally the first port of call while the snagging or warranty period runs. If it keeps failing or isn’t dealt with, we can reseal it properly. In a small place like Mount Pleasant, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
Rather than a set price list, we look at what your job involves: the amount of work, the old material and the access. The price is agreed before we begin.

What we’re called out for in Mount Pleasant
Fresh sealant can be knocked or cut by trades finishing off. A bead disturbed before it has cured may never seal properly, and the problem shows up after you move in.
Any of these means the joints need attention:
- Sealant work across a run of new homes
- Gaps opening as the house dries out and settles
- New-build shower sealant that has already split
- Internal frame sealant that has split
For new homes near Sway station, it’s worth checking the sealant early, while snags are still fresh.
What your quote should include

- Are they insured?
- What guarantee comes with the work

New build mastic in Mount Pleasant: local notes
Mount Pleasant is close to the coast. New homes near the sea put their outside mastic to work from day one, so any gaps are best picked up early. The South East is one of the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
In and around Mount Pleasant, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.

DIY sealant or a professional job?
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
The biggest DIY mistake is sealing over old sealant. New silicone won’t bond to old, so it lifts and traps water and mould underneath. Everything old must be removed first.
What sealant work can’t fix
To be straight with you, there are a few things sealant will not fix:
- Settlement cracks that need a surveyor
- Deciding who is responsible under a builder’s warranty
- Movement caused by a poorly fitted tray or bath
Not sure which it is? You can phone 0345 464 0079 or email us and we’ll tell you honestly.
