Problem with your new-build sealant joints in Bagshot? We cut out the old, prepare the joints and apply the right sealant, with a one-year guarantee.

How the visit works
Every visit runs the same way: we look at the joints together, protect the area around them, carry out the job and clear up. Most jobs take a few hours in a single home. In a smaller place like Bagshot, parking is seldom the issue; lanes, gates and long drives are worth mentioning. For outside work, side access and the height of the joints help us plan.
- We start by going through the snagging items or plot schedule with you.
- Every bit of the old builder’s sealant is cut out down to clean surfaces.
- We clean out the dust and grit left from the build.
- We prime where needed and apply a sealant suited to each joint.
- We tool every joint neatly and tell you when each area can be used.
Before we arrive
- On commercial sites, let us know about site rules
- Let us know about stairs, lifts or work at height
- Keep children and pets away from the work area

New build mastic for homes and businesses in Bagshot
Our new-build work comes in two parts: plot mastic for developers, and putting right failed sealant for people who’ve bought a new home. Both get the same care over preparation since hurried prep is behind a lot of new-build failures. If you have gaps opening as the house dries out and settles and sealant applied over dusty or wet surfaces, we can help, whatever the surface.
If you’ve bought a new home in or near Bagshot, the first year or two is a good time to check the sealant. Common snags include open skirting joints, lifting shower seals and gaps around frames.
Whatever the size of the job, it’s backed by our one-year guarantee in Bagshot and across Surrey.

Your questions about new build mastic in Bagshot
Do you cover smaller places like Bagshot?
Yes, smaller places are covered as well as towns. We work across London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Do you cover Bagshot for new build mastic?
Yes. We work across London and the South East, and Bagshot is part of that. You can phone 0345 464 0079 or drop us an email and let us know what needs doing, and we’ll give you a clear price.
Where do you work from?

Is there a guarantee?
Yes: twelve months. If there’s a problem with our work in that time, tell us and we’ll put it right.
What sealant do you use?
It depends on the joint: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. Brands we use include Arbo and Everbuild.
Will the old sealant be removed?
Always. Sealing over the old bead is the commonest cause of early failure, and it’s something we never do.
When is the best time to reseal in a new build?
It depends on whether water is getting through. Failed seals in wet areas need doing now, but cosmetic gaps can wait for movement to slow.
Is it worth trying it myself?
Some simple jobs can be done by a careful DIYer. The usual mistakes are sealing over old sealant, sealing a damp joint and using too much.
Common problems we fix in Bagshot
Not every new-build joint gets the right sealant: caulk where water collects, or a rigid product on a moving joint. Neither lasts long.
It’s worth asking for a quote if you see:
- Sealant applied over dusty or wet surfaces
- Cracked caulk along new skirting
- Joints pulling apart as timber shrinks
- Plot mastic for developers ahead of handover
For new homes near Bagshot station, it’s worth checking the sealant early, while snags are still fresh.

How we quote for new build mastic
There’s no set price list. What we look at:
- Whether old sealant or filler has to be cut out
- How easy the joints are to reach
- The product the joint needs
- Working hours on commercial sites
Rather than a set price list, we price the job in front of us: how many joints, what’s in them now and how we reach them. The price is agreed before we begin.
What to tell us for a quote
A few details help us give you an accurate quote. When you ask for a quote, tell us:
- Whether it has been sealed before
- Whether it’s a home or a business
- The problem you’ve noticed
- Pictures of the joints, sent by email

Why it’s worth doing now in Bagshot
Water getting past a failed seal in a new build reaches walls and floors that are still settling. Resealing promptly protects the new finishes around it. Homes in smaller places like Bagshot can face more weather, and failed outside joints let damp into walls. Inside, a split seal lets water into floors and panels just as it would anywhere.
Homes and businesses are quoted the same way: how much there is to do, how we reach it and what it needs, plus any working-time requirements on site. Ask us for a quote and we will explain what it covers.
Why us?
- Arbo and Everbuild products
- White, clear, grey or coloured to suit, where the product allows
- ARBOMaster approved applicator
- Homes, businesses and hotels

DIY versus a professional finish
Sealing over old silicone is the commonest DIY error. Silicone doesn’t stick to old silicone, so it lifts and traps water and mould underneath. All the old material has to come out first.
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
How to look after the new joints
Aftercare is simple:
- Do not wait for the house to settle if water is getting through
- Photograph failed sealant before it’s redone
- Report sealant problems to your builder during the snagging period
- Ventilate bathrooms well, especially in the first year
Keep an eye on the joints over the first couple of years. Hairline gaps can open as timber and plaster dry and can be resealed later.
If a shower tray or bath seal splits in the first year, look for movement. Have it resealed, and the tray or bath checked, before it gets worse.
