New build mastic in Great Holcombe, done properly
Dust is the enemy of new-build sealant. We clean every joint thoroughly and prime where the surface and product need it, so the new bead bonds properly rather than sitting on a layer of grit. We work on show homes, windows & doors and plot handovers, and the jobs we see most are frame joints opening as the plaster dries and cracked caulk along new skirting.
For a small place like Great Holcombe, the journey and access are planned in advance, and once on site, the job is the same as anywhere.
The work is covered for a year after we finish. If anything is not right with it, phone 0345 464 0079 or email us.

On the day, there’s very little for you to do. Point us to the joints and we will get on with it. The job generally takes a few hours in a single home, including the tidy-up.

Letting agents often deal with us directly. Send the address, what’s needed and the access arrangements and we’ll give you a quote.
A neglected joint can let water reach the structure, which is a bigger problem in a rented property. Keeping joints in good order is simple maintenance.
DIY versus a professional finish
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions, and the work is guaranteed for a year.
Sealing over old silicone is the commonest DIY error. New silicone won’t bond to old, so it peels away and traps moisture behind it. Everything old must be removed first.
Aftercare tips
Good habits help new joints last longer. Our tips:
- Keep water off fresh sealant until it has cured
- Clean sealant with mild detergent, not abrasives
- Record problems with dated photos
- Act quickly if a seal starts to leak
Clean the sealant with a mild detergent and a soft cloth. Keep scourers and harsh chemicals off it, which can damage the surface.
Early snagging is easier snagging. Small faults turn into leaks if left.

Why deal with it now?
For developers, getting the sealant right first time saves return visits. Every return visit for a failed seal takes time, and they’re avoidable with good preparation. Around Great Holcombe, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
Combining jobs into one visit generally makes better use of the time than several visits. You’ll get one clear quote for the whole job.

What the job involves on each surface
Plot handovers
Good preparation at handover saves snagging later. We clean out building dust before sealing and prime where the product needs it.
Skirting and floors
New homes often develop a gap between skirting and floor. A flexible sealant closes it without cracking like caulk.
Your questions about new build mastic in Great Holcombe
Is Great Holcombe within the area you cover?
Yes. Great Holcombe is within the area we cover, which takes in towns, villages and rural addresses. We work across London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Is new build mastic in Great Holcombe guaranteed?
Every job comes with our 12-month guarantee, wherever it is. We are fully insured, and an ARBOMaster approved applicator.
Should I wait before resealing?
It depends on whether water is getting through. A leaking shower or bath seal should be redone straight away, while small cosmetic gaps can wait a while.
Do I have to be there?
For indoor joints, yes, someone needs to let us in. Once we have agreed the job, you do not need to watch us work.
I rent my home. Can I book you?
We can work for tenants, landlords or agents. Get your landlord’s agreement first.
Is it worth trying it myself?
For a simple, easy-to-reach joint, a careful DIYer can do a reasonable job. The usual mistakes are sealing over old sealant, sealing a damp joint and using too much.
Are you insured?
Yes. We’re fully insured.
Will you just run a new bead over the existing one?
No. Over-sealing traps mould and water and soon fails. All the old sealant comes out before work begins.
