What we do, step by step
On the day, we look over the joints with you first, so there are no surprises. 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 as small as Dunsbury, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We start by going through the snagging items or plot schedule with you.
- The failed sealant is removed completely, with no layer left behind.
- We clean out the dust and grit left from the build.
- Primer goes on where the surface and product need it, then the new sealant.
- Each bead is tooled and the cure times explained.
How to prepare
- Mention if the joints have been sealed before
- Move anything stored near the joints
- On commercial sites, let us know about site rules

How we handle new build mastic in Dunsbury
In a new home, every joint should have a clean, even bead. When the finish is smeared, patchy or already cracking, it’s worth putting right early, before water gets into the floor or walls. We are often asked to deal with cracks appearing as a new home settles and smeared, uneven beads picked up at snagging, across show homes, windows & doors and skirting & floors.
Somewhere as small as Dunsbury, new homes tend to be conversions, self-builds or a few houses rather than an estate. Every one needs its sealant and floor joints done properly, whatever the size of the site.
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.

What else we do in Dunsbury
For landlords and businesses
We work for landlords and agents as well as householders. Sealant work between tenants is a simple way to keep a property in good order.
Letting agents often deal with us directly. Tell us the address, the job and how access works.
Surface by surface
Skirting and floors
As timber and screed dry, skirting and floors shift. We use a flexible product rather than caulk.
Bathrooms and en suites
En suite seals are easy to miss on a snagging list until they leak. A proper reseal keeps water in the tray.
Quotes for new build mastic in Dunsbury
Jobs vary more than people expect. The main factors:
- Working hours on commercial sites
- How easy the joints are to reach
- How much there is to do
- Any mould that needs treating
Some things make a job bigger or smaller: how much old sealant there is and how stubborn it is, whether mould needs treating, and whether we need extra access for height. Your quote takes all of that into account.
What we need to know
What to tell us when you ask for a quote:
- If it’s domestic, commercial or a hotel
- What the problem is, such as mould, gaps, leaks or cracking
- Photos by email, if that’s easy
- Where the property is
It all starts with a short chat. Describe the problem, the location and the size of the job, and we will explain how we’d tackle it. When it suits you, ring 0345 464 0079 or drop us an email.
What new build mastic looks like in Dunsbury
Dunsbury is within about 1 mile of the coast. New homes near the sea put their outside mastic to work from day one, so any gaps are best picked up early. London and the South East are among the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
Whether the job is in Dunsbury itself or nearby, the right material for each joint matters as much as a neat finish.

Signs you need new build mastic in Dunsbury
New homes are full of moisture from plaster, screed and concrete, which takes a year or two to dry out. As it does, timber shrinks and joints open.

- Sealant that never bonded to the surface
- Joints pulling apart as timber shrinks
- Untidy sealant flagged on a snagging list
- Skirting joints opening in the first winter
Around Dunsbury, as everywhere, new build mastic is only as good as the preparation behind it.

FAQs for Dunsbury
Is Dunsbury in your area for new build mastic?
Yes. We work across London and the South East, and Dunsbury is part of that. You can ring 0345 464 0079 or email us and let us know what needs doing, and we will send you a clear quote.
Will you come out to Dunsbury?
Yes, smaller places are covered as well as towns. We work across London and the South East. Just mention lanes, gates or anything else about the route when you book.
Which products do you use?
We choose the sealant for the joint, not the other way round. Movement, water and weather all affect the choice, and we’ll tell you what we are using.
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.
Are you insured?
Yes. We are fully insured, and we can confirm the details when we quote.
Do you work for developers?
Yes. We carry out plot mastic and second-fix sealing for builders and developers. Send us the plot schedule and we’ll quote.
Can I send you my snagging list?
Yes. Send it with pictures and we’ll quote for the sealant items. If something is not sealant, we’ll say so.
Will it make a mess?
Not at all. The area is protected while we work and cleaned up afterwards.
Honest limits
In fairness, there are a few things sealant won’t fix:
- Leaks from pipes, valves or wastes, which need a plumber
- Settlement cracks that need a surveyor
- Your warranty claim itself, which is between you and the builder
If in doubt, call 0345 464 0079 or email us and we’ll say what we think before you book.
Surfaces we seal
- Show homes
- Bathrooms & en suites
- Skirting & floors
- Kitchens
- Windows & doors
- Plot handovers
Why deal with it now?
The builder is generally the first port of call while the snagging or warranty period runs. If it’s slow, or the same joint keeps failing, a proper reseal from a specialist is the next step. Older cottages and farmhouses around Dunsbury can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
Doing several joints on one visit generally makes better use of the time than several visits, so tell us about everything that needs sealing. We will give you a clear price for the lot.
