Is new build mastic in St Mary Hoo guaranteed?

Where is Mr Mastic based?

What do you put in the joint?
Quality sealants from brands including Arbo and Everbuild, chosen to suit the joint. We explain the product when we quote.
Will the old sealant be removed?

Are you ARBOMaster approved?
Yes. We’re ARBOMaster approved, the scheme for applicators of Arbo sealants.
Does someone need to be in?
Access is agreed with you when the job is booked. For inside work, that normally means someone being in.
What happens on the day
A visit follows a simple pattern: we look at the joints together, mask and protect the surrounding surfaces, carry out the job and clear up. It normally takes a few hours for most snagging lists, longer for a run of plots. In a small place like St Mary Hoo, access is normally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- First, the list of joints is agreed from your snagging sheet or plot schedule.
- Every bit of the old builder’s sealant is cut out down to clean surfaces.
- Joints are vacuumed and cleaned of building dust.
- We prime where needed and apply a sealant suited to each joint.
- Each bead is tooled and the cure times explained.
How to prepare
- Move anything stored near the joints
- Try not to wet indoor joints just before the visit
- Mention any leaks or damp you’ve noticed

Advice
Signs you need new build mastic in St Mary Hoo
A new house holds a lot of water from the build, and it dries out over the first couple of years. Drying timber shrinks and pulls joints apart, and sealant that can’t keep up splits.
Most people get in touch after spotting something like this:
- Smeared, uneven beads picked up at snagging
- Cracked caulk along new skirting
- Sealant work across a run of new homes
- Worktop and upstand sealant coming away
Around St Mary Hoo, as everywhere, new build mastic is only as good as the preparation behind it.
What your quote should include
- Whether all the old sealant comes out first
- How long to leave it before use
- Who turns up on the day
- Whether they’re fully insured
When it is not the sealant
Sealant isn’t the answer to every problem, and we’d rather say so up front. Sealant will not put right:
- Leaks from pipes, valves or wastes, which need a plumber
- Your warranty claim itself, which is between you and the builder
- Baths and trays that move too much for sealant to cope with
If in doubt, phone 0345 464 0079 or drop us an email and we will say what we think before you book.
What we seal
- Bathrooms & en suites

- Plot handovers
- Kitchens
How the job changes by surface
Plot handovers
Taking time over preparation reduces return visits. Dust from the build is removed first and primer used where needed.
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.
For landlords and businesses
We work for landlords and letting agents as well as householders. Sealant work between tenants keeps a property looking cared for.
If you manage several properties in or around St Mary Hoo, several properties can go on one quote. Just tell us the addresses and what each one needs, and photos by email help.
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. Everything old must be removed first.
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
What happens if it’s left?
A hairline gap at a skirting can wait, but a leaking seal can’t. Not sure whether yours can wait? You can phone 0345 464 0079 or email us with a few pictures and we’ll give you a straight answer. In a small place like St Mary Hoo, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
A few things move the cost up or down: the old material and how easily it comes out, any mould to treat, and whether we need extra access for height. We take all of that into account in your quote.
Why us?
- White, clear, grey or another colour, product permitting
- Fully insured
- One-year guarantee on every job
