Quotes for new build mastic in Alvescot
We don’t publish a price list, because no two jobs are the same. The quote depends on:
- The number and length of the joints
- When we can work, for business premises
- Mould in or behind the old joints
- How much old sealant there is and how hard it is to remove
Commercial jobs are quoted on the same basis as homes: the amount of work, the access and the products needed. Ask us for a quote and we will explain what it covers.
What to tell us for a quote
To make quoting easier, please include:
- If someone has resealed it before
- Where the job is, and your postcode
- Whether it’s a home or a business
- How we’d reach the joints

New build mastic in Alvescot, done properly
A new build should have a neat, sound bead at every joint. Smeared, patchy or cracked sealant is worth sorting early, before water reaches anything behind it. Typical jobs include worktop and upstand sealant coming away and joints pulling apart as timber shrinks, across plot handovers, show homes and skirting & floors.
Older homes in small places like Alvescot often have timber floors that move with the seasons, which is why skirting and threshold joints need a flexible sealant, not filler.
All our work comes with a one-year guarantee, wherever you are in Oxfordshire.

Leave it or put it right?
Sealant done properly at handover means fewer callbacks. Snagging visits for failed sealant cost time on every plot and most come down to preparation. Older cottages and farmhouses around Alvescot can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
The cost reflects the work involved, not guesswork. That is why we ask about the job first and give you a clear price before we start.
Why book with us
- We agree the colour with you first
- Full insurance on every job

What happens on the day
Once we’re on site, we compare the joints with what we discussed. If we find something unexpected, we talk it through with you first. Most jobs then take a few hours for most snagging lists, longer for a run of plots. Somewhere like Alvescot needs a little journey planning: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.
- Each joint is checked for movement before any work starts.
- 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.
Before we arrive
- On commercial sites, let us know about site rules
- Tell us if parking is tricky
- Plan for the work area to be out of bounds to pets and children

Related advice
Different surfaces, different methods
Bathrooms and en suites
New-build bathrooms and en suites are where sealant fails most often. The old sealant comes out and anti-fungal sanitary silicone goes in after cleaning and priming.
Kitchens
As a new house dries, worktops and walls shift a little, opening gaps behind the upstand. We reseal them with a flexible sealant.
What we are called out for in Alvescot
Baths and trays settle under load once the home is lived in. If a bath wasn’t filled when it was sealed, the bead is stretched the first time it’s used and the sealant may split.
Most people get in touch when they notice one of these:
- Frame joints opening as the plaster dries
- Leaking shower tray seals in a new home
- Sealant applied over dusty or wet surfaces
- Messy sealant that spoils new finishes
Around Alvescot, as everywhere, new build mastic is only as good as the preparation behind it.

Will you come out to Alvescot?
Yes, we do. We work across London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.
Will there be a smell?
Possibly a little. Any smell clears as the sealant cures, and ventilation helps.
Can tenants book the work?
We’re happy to deal with the tenant, landlord or agent. Get your landlord’s agreement first.
Is it normal for sealant to crack in a new home?
Lots of new homes see sealant crack early as timber and plaster dry out. Poor preparation at handover adds to it.

DIY sealant or a professional job?
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is, then guaranteed for a year.
A DIY attempt doesn’t rule out a professional job. We cut it out and start again, so just mention it when you contact us.
