Addlestone New Build Mastic
Our applicators work in Addlestone on plot mastic for developers and snagging failed sealant in new homes. Old sealant removed completely, joints prepared properly and every job guaranteed for a year.

Why it’s worth doing now in Addlestone
Sealant done properly at handover means fewer callbacks. Every return visit for a failed seal takes time, and they’re avoidable with good preparation. Around Addlestone, water from a failed joint in an older home can soak into timber and plaster, and that’s a much bigger job than renewing the sealant.
Leaving a failed joint generally makes the job bigger, not smaller, as water and mould keep getting in. If you are unsure, call 0345 464 0079 or drop us an email for an honest opinion and a quote.

About our new build mastic in Addlestone
Developers send us the plot schedule and we work through it. Bathrooms, en suites, kitchens, frames and skirting are sealed ready for handover using the right product for each joint. We work on bathrooms & en suites, skirting & floors and plot handovers, and people most often call us about skirting joints opening in the first winter and messy sealant that spoils new finishes.
In smaller places like Addlestone, new homes tend to come as small developments or single plots. Each still needs its sealant and floor joints finished properly from day one.
We guarantee the work for a year. If there’s a problem with our work within the year, let us know and we will sort it.

Different surfaces, different methods
Bathrooms and en suites
Shower trays in new homes often move slightly in the first year. The joint is stripped back before the new bead goes in and baths are filled before sealing.
Windows and doors
Draughts around new frames are often a sealant gap. We look at the joints and reseal where needed.
Keeping the joints in good condition
No joint lasts for ever, but care makes a real difference. A few tips:
- Watch for new gaps as the house dries out
- Avoid running a DIY bead over the old one
- Record problems with dated photos
- Open a window or run the fan after bathing
Keep pictures of the joints and any snagging correspondence with your builder. It’s useful if you need to raise other issues later.
Mould takes hold quickly in sealant that has gaps or lifted edges. Dealing with it before it goes black saves a harder job later.
New homes and floors in Addlestone
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.

Questions from Addlestone
I let a flat near Addlestone station. Can you help?
Yes, rental work is part of what we do. You can phone 0345 464 0079 or drop us an email with the address and a few details, and we will give you a fixed price before work begins.
Can you do new build mastic in Addlestone?
Yes. Our work covers London and the South East, and Addlestone is part of that. Just call 0345 464 0079 or email us with a few details of the job.
Do you take out the old sealant first?
Always. Sealing over the old bead is the commonest cause of early failure, so we never do it.
Are you fully insured?
Yes. Full insurance covers our work.
When is the sealant fully cured?
Cure times vary by product and the conditions. Before we leave, we will tell you the cure time.
Do you hold any approvals?
Yes. We hold ARBOMaster approved applicator status.
Is the work guaranteed?
Yes, always. Each job is guaranteed for twelve months.
Can you reseal over the builder’s sealant?
No. Sealing over old sealant looks fine for a few weeks, then lifts. All the old sealant comes out before we start.
What we’re called out for in Addlestone
New homes are full of moisture from plaster, screed and concrete, and it dries out over the first couple of years. As it does, timber shrinks and joints open and the sealant has to cope with the movement.
Most people get in touch when they notice one of these:
- Skirting joints opening in the first winter
- Internal frame sealant that has split
- Sealant that never bonded to the surface
- Plot mastic for developers ahead of handover
In and around Addlestone, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.

DIY versus a professional finish
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
A DIY attempt doesn’t rule out a professional job. We cut it out and start again, so tell us about it when you ask for a quote.
What we do, step by step
Once we are on site, we check the joints match what you told us. If we find something unexpected, we talk it through with you first. After that, the work takes a few hours in a single home. Parking around Addlestone is generally easier than in a town centre, but mention any lanes, gates or long drives. If the job is outside, tell us about side access and how high the joints are.
- We look at why each joint failed, including any movement.
- We remove the failed sealant and clean the joints.
- Joints are dried and primed where the product calls for it.
- Baths are filled with water, then the new sealant is applied.
- We check every joint and leave you with the cure times.
Preparing for the visit
- Try not to wet indoor joints just before the visit
- Keep pets and children clear of the area while we work
- For business premises, tell us about site rules or sign-in
