Should I try it myself first?
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
What happens on the day
Once we are on site, we check the joints match what you told us. If we find something unexpected, we talk it through with you first. Most jobs then take a few hours in a single home. For a job in Great Baddow, we agree the time, the access and parking before the day. Outdoor jobs depend on a dry day, since sealant needs a dry surface.
- 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.
- Joints are vacuumed and cleaned of building dust.
- Primer goes on where the surface and product need it, then the new sealant.
- We tool every joint neatly and tell you when each area can be used.
How to prepare
- Tell us about any water getting in
- Plan for the work area to be out of bounds to pets and children
- Try not to wet indoor joints just before the visit

Related advice
How the job changes by surface
Skirting and floors
As timber and screed dry, skirting and floors shift. Caulk cracks; a flexible sealant moves with it in a colour to suit.
Bathrooms and en suites
New-build bathrooms and en suites are where sealant fails most often. We cut out the failed bead, clean and prime, and reseal with anti-fungal sanitary silicone.
When to call us in Great Baddow
Sealant applied onto damp surfaces does not bond well. Site programmes don’t always leave time for joints to dry.
These are the problems we are asked about most:
- Plot mastic for developers ahead of handover
- Gaps opening as the house dries out and settles
- Frame joints opening as the plaster dries
- Kitchen sealant that has pulled off the wall
In and around Great Baddow, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.

Your questions about new build mastic in Great Baddow
Can you help a landlord with a rental near Chelmsford station?
Yes, rental work is part of what we do. You can ring 0345 464 0079 or email us with the address and a few details, and we will give you a fixed price before work begins.
Do you cover smaller places like Great Baddow?
Yes, we do. Our work covers London and the South East, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
Is it worth resealing while the house is still settling?
It depends on whether water is getting through. Failed seals in wet areas need doing now, but cosmetic gaps can wait for movement to slow.
Which products do you use?
It depends on the joint: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. Brands we use include Arbo and Everbuild.
Are you ARBOMaster approved?
Yes. We’re approved under the ARBOMaster scheme.
Will there be a smell?
It depends on the product. Some products have a noticeable smell, others very little, and any smell fades as they cure.
Can you do several jobs on one visit?
Yes, and it often makes sense. Combining jobs makes good use of the visit, so mention them when you ask for a quote.
Where is Mr Mastic based?
We work from Crawley. Our applicators cover Great Baddow.
