About our new build mastic in Wishaw
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. If you have new-build shower sealant that has already split and sealant work across a run of new homes, we can help.
In a town like Wishaw, older streets sit alongside newer estates. Newer homes need snagging; older ones need their joints renewing.
There’s a 12-month guarantee on every job, large or small.

Common problems we fix in Wishaw
Later trades and the final clean can damage fresh sealant. A bead disturbed before it has cured may never seal properly, and the problem shows up after you move in.
Most people get in touch when they notice one of these:
- Cracks appearing as a new home settles
- Skirting joints opening in the first winter
- Second-fix sealing on new plots
- Smeared, uneven beads picked up at snagging
In and around Wishaw, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.
Questions to ask before booking
- Whether all the old sealant comes out first
- Which sealant they’ll use, and why
- Who does the work, and how experienced they are
- What happens if the job turns out different
Landlord and commercial work in Wishaw
For anyone letting property in or around Wishaw, several properties can be quoted together. Send us the addresses and the work at each, and photos by email help.
Letting agents often deal with us directly. Send the address, what’s needed and the access arrangements.
What affects the quote in Wishaw
Your quote is based on your job. We look at:
- The number and length of the joints
- Whether old sealant or filler has to be cut out
- Any working-time requirements on site
- The product the joint needs
Instead of a standard rate, we price the job in front of us: how many joints, what’s in them now and how we reach them. You will know the price before we begin.
Helping us quote
The more you tell us, the more accurate the quote. When you get in contact, it helps to mention:
- Where the property is
- What the problem is, such as mould, gaps, leaks or cracking
- If someone has resealed it before
- How many joints, rooms or windows are involved
We quote each job on its own. Just send an email to info@mrmastic.co.uk with the details, and pictures are welcome.
How to look after the new joints
No joint lasts for ever, but care makes a real difference. Our tips:
- Avoid scourers and strong chemicals on sealant
- Wait for the cure time before using a resealed shower
- Open a window or run the fan after bathing
- Do not wait for the house to settle if water is getting through
Leave the sealant for the cure time we give you before showering or bathing. Most silicones need around a day to cure enough for use.
The sooner you deal with untidy or cracking sealant, the less there is to put right. Small faults turn into leaks if left in a busy bathroom.
Surface by surface
Windows and doors
Draughts around new frames are often a sealant gap. We check and reseal the frame edges.
