New build mastic for homes and businesses in Newchurch
In a new home, every joint should have a clean, even bead. When the finish is smeared, patchy or already cracking, it’s worth putting right early, before water gets into the floor or walls. We work on bathrooms & en suites, plot handovers and windows & doors, and the jobs we see most are sealant that never bonded to the surface and cracks appearing as a new home settles.
Work in a small place like Newchurch just needs the journey and access planning, and once on site, the job is the same as anywhere.
There’s a 12-month guarantee on every job, whatever its size.

How to look after the new joints
Looking after new joints is easy:
- Clean sealant with mild detergent, not abrasives
- Report sealant problems to your builder during the snagging period
- Keep water off fresh sealant until it has cured
- Get a leaking seal dealt with right away
Follow the cure time we give you before the area gets wet. Most silicones need around a day before water reaches them.
Don’t let the snagging period run out with sealant problems unreported. Once it ends, the repair may be down to you, so raise it early.
How it works
When we get to you, we check the joints match what you told us. If anything is different, we explain it before carrying on. After that, the work takes anything from a few hours to several days, depending on the number of plots. For a village or hamlet like Newchurch, the journey is planned in advance: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.
- First we work through your snagging list or plot schedule with you.
- We cut out every bit of the failed or messy sealant.
- Surfaces are cleaned of building dust and primed where needed.
- A sealant chosen for each area goes in and is tooled smooth.
- We check every joint and tell you how long each needs to cure.
How to prepare
- Keep pets and children clear of the area while we work
- Try not to wet indoor joints just before the visit
- Tell us about any previous sealing or DIY attempts

Your questions about new build mastic in Newchurch
Can you help a landlord with a rental near Ham Street station?
Yes, rental work is part of what we do. You can call 0345 464 0079 or email us with the address and a few details, and we’ll give you a fixed price before work begins.
Do you cover smaller places like Newchurch?
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 match the sealant colour to my new kitchen or bathroom?
It depends on the joint: white or clear for most sanitary joints, colours for worktops, floors and frames. We’ll agree it with you first.
Do you take out the old sealant first?
Yes, always, and completely. New silicone does not stick to old silicone, so any old material comes out before anything new goes in.
Do you hold any approvals?
Yes. Mr Mastic is an ARBOMaster approved applicator, and we’re fully insured.
How long does new build mastic take?
A typical job takes a few hours in a single home. Your quote will say how long we expect yours to take.
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 any work starts.
Is it worth resealing while the house is still settling?
Where water is getting through, do not wait. Hairline cosmetic gaps can wait until the house has settled.
What we’re called out for in Newchurch
New homes are full of moisture from plaster, screed and concrete, which takes a year or two to dry out. As it does, timber shrinks and joints open, and sealant that cannot keep up splits.
Look out for any of the following:
- Shower seals failing in the first year or two
- Messy sealant that spoils new finishes
- Sealant applied over dusty or wet surfaces
- Second-fix sealing on new plots
For new homes near Ham Street station, it’s worth checking the sealant early, while snags are still fresh.
Before you book anyone
- When the joint can take water or movement
- How much experience the applicator has
- How the colour is chosen
- What happens if they find a problem under the old sealant
DIY versus a professional finish
If you are set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it doesn’t work out, we can still put it right.
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
What the job involves on each surface
Windows and doors
A draught at a new window can be a missed or failed joint. We look at the joints and reseal where needed.
Skirting and floors
Gaps under skirting are one of the most common new-build snags. We seal it with a flexible sealant that copes with the movement.
Leave it or put it right?
Small cosmetic gaps can wait for the house to settle, but a leaking seal can’t. If you’re unsure which you have, phone 0345 464 0079 or send us an email with pictures and we will tell you. In a small place like Newchurch, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
The cost depends on the size of the job, how hard the old material is to remove and how easy the joints are to reach. We give a clear quote before we start.
