- Sealant that never bonded to the surface
New build mastic for homes and businesses in Aston
Some new-home owners let the house settle before resealing. That makes sense for small gaps that are just cosmetic, but a failed shower or bath seal shouldn’t wait. If you have gaps opening as the house dries out and settles and worktop and upstand sealant coming away, we can put it right, whatever the surface.
In a village or hamlet like Aston, new homes are more likely to be a barn conversion or a handful of houses than a big estate. Every one needs its sealant and floor joints done properly, whatever the size of the site.
Each job carries a 12-month guarantee.

What happens if it’s left?
If you are still in the builder’s snagging or warranty period, ask them to put it right first. If it’s slow, or the same joint keeps failing, a proper reseal from a specialist is the next step. Where a wall is exposed, as many are in small places like Aston, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
Instead of a standard rate, we look at what your job involves: how many joints, what’s in them now and how we reach them. You will know the price before we begin.

What we do, step by step
All our tools and materials come with us in the van, so there’s nothing for you to buy. Once we’ve agreed what’s being done, the area is protected and the work begins. Most jobs take anything from a few hours to several days, depending on the number of plots. Somewhere as small as Aston, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- First we work through your snagging list or plot schedule with you.
- The old bead comes out in full, with no layer left behind.
- We clean off dust from the build and prime the surfaces where the product needs it.
- A sealant chosen for each area goes in and is tooled smooth.
- Each area is checked and left with its cure time.
Preparing for the visit
- Mention if the joints have been sealed before
- Plan for the work area to be out of bounds to pets and children
- Let us know about parking restrictions

Advice
New build mastic in Aston: local notes
Compared with the north and west, the South East gets less rain, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
Around Aston, as everywhere, new build mastic is only as good as the preparation behind it. If you’ve bought a new home near Henley-On-Thames station, the sealant around baths, showers and frames is worth checking in the first year or two.

Keeping the joints in good condition
Simple care keeps the joints in good condition. We recommend:
- Wipe joints with warm soapy water
- Get a leaking seal dealt with straight away
- Check bath and shower seals every few months as the house settles
- Raise failed sealant with the developer while you are covered
Clean the sealant with a mild detergent and a soft cloth. Avoid abrasive pads and strong solvents, which can damage the surface.
Lifting sealant traps moisture and mould behind it. Resealing before mould gets in keeps the job straightforward.
Common questions in Aston
Is Aston in your area for new build mastic?
Yes, Aston is within the area we cover. Our work covers London and the South East. Just ring 0345 464 0079 or email us with a few details of the job.
Is Aston 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.
Will you just run a new bead over the existing one?
No. The old sealant is cut out fully, the joint cleaned and primed where needed, and a new bead applied.
What colour sealant will you use?
The colour is chosen to suit the tiles, worktop or frame. Let us know your preference when you ask for a quote.
Is it worth resealing while the house is still settling?
If the seal has failed and water is getting in, do it now. Small gaps that are just cosmetic can be resealed once movement has slowed.
Where do you work from?
Our base is in Crawley, and we cover South East England, London and all of Scotland.
How long does new build mastic take?
As a guide, most jobs take a few hours in a single home. Bigger jobs take longer.
Do you hold any approvals?
Yes. ARBOMaster is the approved applicator scheme for Arbo sealants, and we’re part of it.

Different surfaces, different methods
Kitchens
New-kitchen sealant is often applied in a rush. We take it out and reseal neatly, colour-matched where it shows.
Show homes
Show homes need sealant that looks right from day one. We lay neat, even beads in colours to suit the finishes.
DIY sealant or a professional job?
A DIY attempt does not rule out a professional job. We remove it and do the joint properly, so just mention it when you contact us.
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is, then guaranteed for a year.

What we can’t put right
To be straight with you, some problems need a different trade:
- Leaking fittings rather than failed sealant
- Cracked trays, tiles or worktops
- Settlement cracks that need a surveyor
