Aftercare tips
Good habits help new joints last longer. A few tips:
- Resist patching a failed seal with a tube from the DIY shop
- Put sealant faults on your snagging list early
- Photograph failed sealant before it’s redone
- Watch for new gaps as the house dries out
Avoid standing on the rim of the bath or the edge of the tray while the sealant cures. Report any movement in a bath or tray.
Report failed sealant to the builder while you’re in the snagging period. Once it ends, the repair may be down to you.
New build mastic for homes and businesses in Great Haseley
Some owners wait for the first year’s movement before having joints redone. That makes sense for small gaps that are just cosmetic, but a failed shower or bath seal shouldn’t wait. Common call-outs are for skirting joints opening in the first winter and new-build shower sealant that has already split, on show homes, plot handovers and skirting & floors.
For a small place like Great Haseley, the journey and access are planned in advance, and the work itself is the same as on any site.
Our work is backed for twelve months.

How we quote for new build mastic
We don’t publish a price list. What we look at:
- The number of rooms or windows
- How easy the joints are to reach
- Any working-time requirements on site
- Any mould that needs treating

- How many joints, rooms or windows are involved
- Where the property is
- If someone has resealed it before
Call for a quick quote, or email us if that’s easier. Tell us about the joints that need doing and we’ll explain what’s involved and send you a clear quote.
Common questions in Great Haseley
What guarantee comes with new build mastic in Great Haseley?
Every job comes with our 12-month guarantee, wherever it is. We’re fully insured, and an ARBOMaster approved applicator.
Is Great Haseley in your area for new build mastic?
Yes. Our work covers London and the South East, and Great Haseley is part of that. You can phone 0345 464 0079 or drop us an email and tell us what needs doing, and we’ll send you a clear quote.
Can tenants book the work?
We can work for tenants, landlords or agents. Just make sure your landlord agrees.
Are you ARBOMaster approved?
Yes. We hold ARBOMaster approved applicator status.
Do I have to be there?
We need access to the joints, so we’ll agree that with you when we book. Indoors, that normally means someone at home.
What information do you need?
Just the basics: where it is, what you’ve noticed and how we reach it. Then call 0345 464 0079 or drop us an email.
Do you use white or clear sealant?
It depends on the joint: white or clear in most bathrooms, and a colour to suit worktops, frames and floors elsewhere. We will agree it with you first.
Can landlords and businesses book you?
Yes. As well as homeowners, we work for landlords, agents, businesses and hotels.
Can I do it myself?
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is, and the work is guaranteed for a year.
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
What new build mastic looks like in Great Haseley
Compared with the north and west, the South East gets less rain, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
For jobs in and around Great Haseley, choosing the right material for each joint is as important as a tidy finish. In and around Great Haseley, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.

When something else is needed
A few problems are outside what sealant work can do:
- Broken tiles or a split tray

Work for landlords, hotels and businesses

Mouldy or split sealant often shows up at the end of a tenancy, and it’s easy to sort out between tenants. We can quote for more than one property at once.
How the visit works
On the day, we look over the joints with you first, so you know exactly what we’re doing. Surfaces next to the work are protected before any work starts. Most jobs take a few hours for most snagging lists, longer for a run of plots. Somewhere like Great Haseley needs a little journey planning: tell us about narrow lanes, gates, long drives and where we can park. We bring what the job needs, so it can be finished in one trip where possible.
- First, the list of joints is agreed from your snagging sheet or plot schedule.
- The failed sealant is removed completely.
- Joints are vacuumed and cleaned of building dust.
- 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
- Where the joints are inside, avoid wetting them before we arrive
- On commercial sites, let us know about site rules
- Tell us about access, such as stairs, a lift or high-level joints
