What we’re called out for in Tollesbury
Sealant is often one of the last jobs before handover. Dusty, unprimed joints are common, and the sealant sits on grit instead of the surface.
Any of these means the joints need attention:
- Joints pulling apart as timber shrinks
- Shower seals failing in the first year or two
- Frame joints opening as the plaster dries
- Beads laid onto grit and dust from the build
For jobs in and around Tollesbury, choosing the right material for each joint is as important as a tidy finish.
Questions to ask before booking
- What the cure time is
- What guarantee comes with the work
- How the colour is chosen
- What the quote includes, VAT included or not
About our new build mastic in Tollesbury
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. If you are dealing with skirting joints opening in the first winter and untidy sealant flagged on a snagging list, we can put it right.
In a village or hamlet like Tollesbury, new homes are more likely to be a barn conversion or a handful of houses than a big estate. Each still needs its sealant and floor joints finished properly.
We guarantee the work for a year. If something is not right with it in that time, tell us and we will put it right.

How it works
You don’t need to clear the whole room or building, only the area right around the joints. Everything nearby is protected, and the work takes a few hours in a single home for a typical job. Somewhere as small as Tollesbury, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- We start by going through the snagging items or plot schedule with you.
- The failed sealant is removed completely 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.
Getting ready for the visit
- Keep pets and children clear of the area while we work
- Mention any leaks or damp you’ve noticed
- Tell us if parking is tricky

Quotes for new build mastic in Tollesbury
You’ll get a clear quote before we start. It’s based on:
- The size of the job
- The type of sealant required
- How many areas need sealing

Every job is a little different, so each one gets its own quote. Size, access and the product the joint needs all make a difference.
Asking for a quote
You don’t need to know the technical terms. It helps if you can tell us:
- Whether it’s a home or a business
- If someone has resealed it before
- Where the job is, and your postcode
- Roughly how big the job is
For a quick quote, get us on the phone, or send an email if you’d rather. Tell us about the joints that need doing and we will explain what’s involved before giving you a price.
DIY versus a professional finish
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
A DIY attempt doesn’t rule out a professional job. We remove it and do the joint properly.
What happens if it’s left?
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. Around Tollesbury, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
There are no prices on our website, because the cost depends so much on the job itself. Call for a quick quote.

Common questions in Tollesbury
Is Tollesbury in your area for new build mastic?
Yes, Tollesbury is within the area we cover. Our work covers London and the South East. You can call 0345 464 0079 or drop us an email and tell us what needs doing.
Is Tollesbury within the area you cover?
Yes, we do. Our work covers London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.
What do you put in the joint?
The product depends on the job: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. 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.
What do you need from me for a quote?
Just the basics: the address or postcode, what’s wrong and any access issues. After that, simply call 0345 464 0079 or drop us an email.
Is it messy?
No. The area is protected while we work and cleaned up afterwards.
Can you do plot mastic on a new development?
Yes. Second-fix sealing in bathrooms, kitchens, frames and floors is part of what we do. Good preparation keeps snagging to a minimum.
Who should fix failed sealant in a new build?
While the snagging or warranty period runs, the builder should be your first contact. If it isn’t sorted, or keeps failing, get in touch with us.

Keeping the joints in good condition
After the cure time, these simple habits help:
- Avoid running a DIY bead over the old one
- Keep water off fresh sealant until it has cured
- Check bath and shower seals every few months as the house settles
- Wipe joints with warm soapy water
Keep the bathroom ventilated, especially in the first year. Run the fan or open a window after bathing to help keep mould away.
Do not let the snagging period run out with sealant problems unreported. After that, putting it right may fall to you, so raise it early.
