How the job changes by surface
Windows and doors
The gap between a new frame and its plaster reveal often opens up. We cut out the cracked bead and reseal with a flexible sealant in a matching colour.
Skirting and floors
Floors and skirting move as the house dries and the heating runs. Caulk cracks; a flexible sealant moves with it in a colour to suit.
New build mastic for homes and businesses in Fulking
A new house keeps drying out and settling for its first couple of years. Timber dries and shrinks, and baths and trays settle, so sealant that was laid quickly before handover often cracks. If you have skirting joints opening in the first winter and internal frame sealant that has split, we can help, on bathrooms & en suites, plot handovers and windows & doors alike.
Work in a small place like Fulking just needs the journey and access planning, and once on site, the job is the same as anywhere.
All of our work is guaranteed for twelve months, and the guarantee is the same wherever you are.

Why act early in Fulking
Resealing everything on a snagging list in one visit is normally simpler than chasing joints one at a time. You get one visit and one clear quote. Older cottages and farmhouses around Fulking can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
Instead of a standard rate, 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 Fulking clients choose us
- Fully insured
- Neat joints and a tidy finish

How we quote for new build mastic
For a quick quote, just ask. The main things that affect it are:

- The number and length of the joints
- Working hours on commercial sites
- The product the joint needs
A few things move the cost up or down: the old material and how easily it comes out, any mould to treat, and whether we need extra access for height. Your quote takes all of that into account.

Do you need new build mastic in Fulking?
New homes are full of moisture from plaster, screed and concrete, and it dries out over the first couple of years. As it does, timber shrinks and joints open, and sealant that cannot keep up splits.
It’s worth asking for a quote if you see:
- Sealant work across a run of new homes
- New-build shower sealant that has already split
- Beads laid onto grit and dust from the build
- Joints pulling apart as timber shrinks
Around Fulking, as everywhere, new build mastic is only as good as the preparation behind it.
Questions to ask before you book
- How long to leave it before use
- Is the old sealant removed completely?
- Which colour the sealant will be
- What guarantee comes with the work

At the end, we look at the finished work together. The work normally takes a few hours for most snagging lists, longer for a run of plots, depending on the amount of work.

- Each joint is checked for movement before any work starts.
- We remove the failed sealant and clean the joints.
- We make sure the joints are dry and prime them if needed.
- Baths are filled with water, then the new sealant is applied.
- The finished joints are checked and the cure times given.
Preparing for the visit
- Tell us about access, such as stairs, a lift or high-level joints
