New Build Mastic in North Crawley
We cover North Crawley for plot mastic for developers and snagging failed sealant in new homes. Old sealant removed completely, joints prepared properly and every job guaranteed for a year.
- Second-fix sealing on new plots

The process
At the end, we look at the finished work together and explain the cure time. The work normally takes a few hours in a single home, depending on the size of the job. Somewhere as small as North Crawley, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- Each joint is checked for movement before we start.
- We remove the failed sealant and clean the joints.
- We make sure the joints are dry and prime them if needed.
- New sealant goes in, with baths filled first so they’re at their heaviest.
- The finished joints are checked and the cure times given.
Getting ready for the visit
- Plan for the work area to be out of bounds to pets and children
- Move anything stored near the joints
- On commercial sites, let us know about site rules

Can I do it myself?
If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it does not work out, we can still put it right.
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.
New build mastic around North Crawley

Why it’s worth doing now in North Crawley
It often makes sense to do all the sealant items on a snagging list together. You get one visit and one clear quote for the lot. Around North Crawley, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
A few things move the cost up or down: the old material and how easily it comes out, whether mould needs treating, and whether the work is at height. Your quote takes all of that into account.

When to call us in North Crawley
Once people move in, baths and trays take weight and bed down. If a bath wasn’t filled when it was sealed, the bead is stretched the first time it’s used and can tear.
Any of these means the joints need attention:
- Plot mastic for developers ahead of handover
- Frame joints opening as the plaster dries
- Worktop and upstand sealant coming away
- Cracks appearing as a new home settles
In and around North Crawley, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.

- When the joint can take water or movement
- What preparation is included
- Who turns up on the day
Keeping the joints in good condition
So the new joints stay in good condition:
- Wipe joints with warm soapy water
- Raise failed sealant with the developer while you’re covered
- Don’t seal over failed sealant yourself
- Keep water off fresh sealant until it has cured
Watch the joints as the house settles. Small gaps can appear as the house dries and can be resealed later.
If a shower tray or bath seal splits in the first year, look for movement. Getting it resealed properly, and any movement checked, stops it recurring.
Surface by surface
Plot handovers
Send us the schedule and any sealant specification. We seal bathrooms, kitchens, frames and floors.
Show homes
Tired or marked sealant in a show home can be renewed. The old bead comes out and a clean new one goes in.
When something else is needed
We will not take on work that won’t last, so here’s what sealant can’t put right:
- Your warranty claim itself, which is between you and the builder
- A tray or bath that isn’t properly supported, until it’s fixed
- Leaks from pipes, valves or wastes, which need a plumber
If in doubt, call 0345 464 0079 or send us an email and we’ll say what we think before you book.

Your questions about new build mastic in North Crawley
Do you cover North Crawley for new build mastic?
Yes. Our work covers London and the South East, and North Crawley is part of that. You can phone 0345 464 0079 or send us an email and let us know what needs doing.
Is new build mastic in North Crawley guaranteed?
Every job comes with our one-year guarantee, wherever it is. We’re also fully insured and ARBOMaster approved.
Can new sealant go on top of the old bead?
No. Over-sealing traps mould and water and soon fails. We remove every bit of the old bead before resealing.
Do you work for developers?
Yes. We work through plots to your schedule. Get in touch with the number of plots and the scope and we will quote.
When is the best time to reseal in a new build?
Any seal that is leaking should be redone straight away. For small cosmetic gaps, waiting until the house has settled can save doing them twice.
How long does the job take?
Most jobs take anything from a few hours to several days, depending on the number of plots, including the preparation. Your quote will say how long we expect yours to take.
Should I go to my builder first?
Report it to the builder first while you are covered. Once that’s done, or if they won’t put it right, we can reseal it properly.
Is it worth trying it myself?
It depends on the job. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional, while a short indoor joint may be within reach.
