What sealant work can’t fix
Honest advice matters more to us than a booking, so here’s what new sealant will not do:
- Leaking fittings rather than failed sealant
- Cracking that points to a structural problem
- A tray or bath that is not properly supported, until it’s fixed

About our new build mastic in Ashburnham
We carry out plot mastic and second-fix sealing for builders, and snagging reseals for new-home owners. Both get the same care over preparation since hurried prep is behind a lot of new-build failures. If you have untidy sealant flagged on a snagging list and beads laid onto grit and dust from the build, we can help.
Work in a small place like Ashburnham just needs the journey and access planning, and the work itself is the same as on any site.
You’re covered for a year from the day we finish. If anything is not right with it, call 0345 464 0079 or send us an email.

Why act early in Ashburnham
If you’re still in the builder’s snagging or warranty period, ask them to put it right first. If it keeps failing or isn’t dealt with, we can reseal it properly. Older cottages and farmhouses around Ashburnham can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
Rather than a set price list, we look at what your job involves: the amount of work, the old material and the access. The price is agreed before we begin.
Why choose Mr Mastic in Ashburnham

What new build mastic looks like in Ashburnham
Rainfall in the South East is lower than in much of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
Around Ashburnham, as everywhere, new build mastic is only as good as the preparation behind it. If you’ve bought a new home near Battle station, the sealant around baths, showers and frames is worth checking in the first year or two.

Will there be a smell?

What does new build mastic cost?
The cost depends on the size of the job, access and how much old sealant has to come out. Ask us for a quote and we will talk you through it.
Can I add another job to the visit?
Of course. Combining jobs makes good use of the visit, so mention them when you ask for a quote.
What sealant do you use?
Quality sealants from brands including Arbo and Everbuild, chosen to suit the joint. We explain the product when we quote.
My new home is still under warranty. Should I contact you?
Start with the builder if you are in the snagging or warranty period. Once that’s done, or if they will not put it right, we can reseal it properly.

Should I try it myself first?
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
What happens on the day
Good joint work is mostly preparation, so that is where we spend the time. Joints are cleaned back and dried before anything new goes in. In total, it usually takes a few hours in a single home. In a small place like Ashburnham, access is normally 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.
- Every bit of the old builder’s sealant is cut out, with no layer left behind.
- Joints are vacuumed and cleaned of building dust.
- Primer goes on where the surface and product need it, then the new sealant.
- Each bead is tooled and the cure times explained.
Preparing for the visit
- Move anything stored near the joints
- Let us know about parking restrictions
- Tell us about any previous sealing or DIY attempts
Ask for a quote
Call for a quick quote, or email us if that’s easier. Tell us about the joints that need doing and we will explain what’s involved and give you a clear quote.

How to look after the new joints
How long the joints last depends on use and care. Here’s what we suggest:
- Put sealant faults on your snagging list early
- Open a window or run the fan after bathing
- Act quickly if a seal starts to leak
- Wipe joints with warm soapy water
Keep photos of the joints and any snagging correspondence with your builder. It’s useful if you need to raise other issues later.
The sooner you deal with untidy or cracking sealant, the less there is to put right. Left alone, a small crack can become a leak over time.
