New-build mastic & snagging in Crowhurst, East Sussex
Plot mastic for developers and snagging failed sealant in new homes for homes and businesses in Crowhurst and across East Sussex. Fully insured, ARBOMaster approved and guaranteed for a year.
- Smeared, uneven beads picked up at snagging
- Sealant applied over dusty or wet surfaces
- Skirting joints opening in the first winter
How we handle new build mastic in Crowhurst
We never seal over a failed new-build bead. Fresh silicone can’t bond to the old layer, so it all comes out before we clean, dry and reseal. We work on plot handovers, windows & doors and bathrooms & en suites, and people most often call us about cracked sealant around new window and door frames and joints pulling apart as timber shrinks.
Older homes in small places like Crowhurst often have timber floors that move with the seasons, so skirting and threshold joints need a flexible sealant rather than a rigid filler.
A one-year guarantee comes as standard.

Can I do it myself?
A DIY attempt doesn’t rule out a professional job. We remove it and do the joint properly, so just mention it when you contact us.
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.

What affects the cost of new build mastic
We do not publish a price list. What we look at:
- The type of sealant required
- How much old sealant there is and how hard it is to remove
- Any working-time requirements on site
- How easy the joints are to reach
Doing several joints on one visit normally makes better use of the time than several visits. We’ll send you a clear quote for the lot.
What to tell us for a quote
There’s no need for technical detail. It helps if you can tell us:
- Pictures of the joints, sent by email
- Where the job is, and your postcode
- The type of property
- Roughly how big the job is
For a quick quote, get us on the phone, or email us if that’s easier. Describe what needs sealing and we will explain what’s involved before giving you a price.
Signs you need new build mastic in Crowhurst
Fresh sealant can be knocked or cut by trades finishing off. A bead disturbed before it has cured may never seal properly, and the problem shows up after you move in.
These are the problems we’re asked about most:
- Gaps between new skirting and floors
- Gaps behind new kitchen upstands
- Frame joints opening as the plaster dries
- Sealant work across a run of new homes
Around Crowhurst, as everywhere, new build mastic is only as good as the preparation behind it.
Questions to ask before you book
- Whether the sealant suits the joint
- What guarantee comes with the work
- Which colour the sealant will be
- What the cure time is
How the visit works
We work through the job in order: protection first, then preparation, sealing and a tidy-up. For most jobs that takes a few hours in a single home, and the area is left clean. In a small place like Crowhurst, access is generally 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.
- The failed sealant is removed completely, with no layer left behind.
- We clean out the dust and grit left from the build.
- We prime where needed and apply a sealant suited to each joint.
- Each bead is tooled and the cure times explained.
Before we arrive
- Tell us about access, such as stairs, a lift or high-level joints
- For indoor joints, keep the area dry beforehand if you can
- Mention any parking rules near the property

Related advice
Why act early in Crowhurst
It often makes sense to do all the sealant items on a snagging list together. It’s one visit, one quote and one set of cure times. Around Crowhurst, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
Leaving a failed joint normally makes the job bigger, not smaller. If you are unsure, phone 0345 464 0079 or drop us an email and we will give you an honest view and a quote.

When something else is needed
We’d rather tell you now than do work that won’t last, so these are the limits:
- A tray or bath that isn’t properly supported, until it’s fixed
- Leaking fittings rather than failed sealant
- Deciding who is responsible under a builder’s warranty
If in doubt, call 0345 464 0079 or send us an email and we will say what we think.
