New build mastic for homes and businesses in Mount Pleasant
Dust is the enemy of new-build sealant. Each joint is cleaned of dust and primed where the product calls for it, so the new bead bonds properly instead of bonding to the dust. If you are dealing with sealant work across a run of new homes and skirting joints opening in the first winter, we can put it right.
Around Mount Pleasant, older homes often have timber floors that move through the year, so skirting and threshold joints need a flexible sealant rather than a rigid filler.
All of our work is guaranteed for twelve months, in Mount Pleasant and everywhere else we cover.

Common questions in Mount Pleasant
Is Mount Pleasant within the area you cover?
Yes, we do. 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.
Can you do new build mastic in Mount Pleasant?
Yes, Mount Pleasant is within the area we cover. We work across London and the South East. Just phone 0345 464 0079 or email us with a few details of the job, and we will send you a clear quote.
I’m a tenant. Can you help?
We’re happy to deal with the tenant, landlord or agent. Just make sure your landlord agrees.
Can you work on commercial sites?
Yes. We work in offices, washrooms, hotels and other commercial premises. We can talk about working times when we quote.
Will the old sealant be removed?
Yes. Sealing over the old bead is the commonest cause of early failure, so we never do it.
What do you need from me for a quote?
A short description and the location, plus pictures if you have them. We will ask anything else we need to know.
Are you ARBOMaster approved?
Yes. ARBOMaster is the approved applicator scheme for Arbo sealants, and we’re part of it.
What sealant do you use?
It depends on the joint: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. Brands we use include Arbo and Everbuild.
What new build mastic looks like in Mount Pleasant
Rainfall in the South East is lower than in much of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.

Landlord and commercial work in Mount Pleasant
From a single let to a portfolio, you get the same standard of work: the old material taken out, careful preparation and a 12-month guarantee.
Mouldy or split sealant often shows up at the end of a tenancy, and it’s easy to sort out between tenants. We can quote for more than one property at once.
How to look after the new joints
To keep the joints looking good and working properly:
- Raise failed sealant with the developer while you are covered
- Get a leaking seal dealt with straight away
- Open a window or run the fan after bathing
- Check bath and shower seals every few months as the house settles
Wipe the sealant with warm soapy water. Keep scourers and harsh chemicals off it.
Lifting sealant traps moisture and mould behind it. Dealing with it before it goes black saves a harder job later.
When something else is needed
Sealant is not the answer to every problem, and we’d rather say so up front. It will not solve:
- Your warranty claim itself, which is between you and the builder
- Movement caused by a poorly fitted tray or bath
- Settlement cracks that need a surveyor
Not sure which it is? You can call 0345 464 0079 or drop us an email and we will tell you honestly before you book.

Common problems we fix in Mount Pleasant
Not every new-build joint gets the right sealant: decorators’ caulk in a wet area, or a stiff sealant where there’s movement. Neither lasts long.
The problems people usually mention when they call are:
- Gaps opening as the house dries out and settles
- Cracked sealant around new window and door frames
- Smeared, uneven beads picked up at snagging
- Sealant work across a run of new homes
If you’ve bought a new home near Stansted Mountfitchet station, the sealant around baths, showers and frames is worth checking in the first year or two.

Different surfaces, different methods
Bathrooms and en suites
New-build bathrooms and en suites are where sealant fails most often. We cut out the failed bead, clean and prime, and reseal with anti-fungal sanitary silicone.
Show homes
Show homes need sealant that looks right from day one. We lay neat, even beads in colours to suit the finishes.
