About our new build mastic in Terriers
Some new-home owners let the house settle before resealing. For small cosmetic gaps, that’s reasonable, but a failed shower or bath seal shouldn’t wait. We work on skirting & floors, bathrooms & en suites and plot handovers, and people most often call us about sealant that never bonded to the surface and cracked sealant around new window and door frames.
In and around Terriers, floors range from older timber boards to tiles and newer finishes, from timber that moves with the seasons to tiles laid on concrete. Skirting and threshold joints need a sealant that suits the floor.
You get a 12-month guarantee, the same in Terriers as everywhere else we work.

New build mastic around Terriers

What affects the quote in Terriers
Call for a quick quote. The main things that affect it are:
- Which sealant suits the joint
- Mould in or behind the old joints
- When we can work, for business premises
- The number and length of the joints
No two jobs are quite the same, so we quote each one individually. The number of joints, how easy they are to reach and the sealant needed all make a difference.
Asking for a quote
When you contact us, it’s useful to know:
- If it’s domestic, commercial or a hotel
- What the problem is, such as mould, gaps, leaks or cracking
- Any previous sealing or DIY work
- How many joints, rooms or windows are involved
Call for a quick quote, or email us if that is easier. Tell us about the joints that need doing and we will talk you through the work.
DIY versus a professional finish
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is.
If you are set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it doesn’t work out, we can still put it right.

What else we do in Terriers
Landlord and commercial work in Terriers
Landlords and letting agents in Terriers can book us as well as householders. Sealant work between tenants keeps a property looking cared for.
In hotels, rooms out of use cost money, so we plan the work room by room around your bookings where we can. Hotel work is part of what we do, alongside homes and businesses.
Aftercare tips
No joint lasts for ever, but care makes a real difference. A few tips:
- Look at the sealant regularly in the first couple of years
- Act quickly if a seal starts to leak
- Keep photos and emails about snagging items
- Report sealant problems to your builder during the snagging period
Keep an eye on the joints over the first couple of years. Small gaps can appear as the house dries.
Mould takes hold quickly in sealant that has gaps or lifted edges. Resealing before mould gets in keeps the job straightforward.
Surface by surface
Windows and doors
Internal joints between frames and plaster often crack as a new house dries. We cut out the cracked bead and reseal with a flexible sealant.

Terriers: your questions answered
Can you help a landlord with a rental near High Wycombe station?
Yes. We work for letting agents and landlords as well as householders. You can call 0345 464 0079 or send us an email with the details for a clear quote.
Will you come out to Terriers?
Yes, Terriers is covered. We work across London and the South East, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
Why has my new-build shower seal failed already?
New homes dry out and move in their first couple of years, and sealant is often rushed onto dusty, unprimed surfaces. Both lead to early failure.
When is the sealant fully cured?
Different products cure at different speeds, so follow the cure time we give you.
Where do you work from?
Mr Mastic is based in Crawley. Our applicators cover Terriers.
Are you fully insured?
Yes. We’re fully insured.
When is the best time to reseal in a new build?
Where water is getting through, do not wait. Hairline cosmetic gaps can wait until the house has settled.
Can you do plot mastic on a new development?
Yes. Plot mastic and second-fix sealing for developers is part of our work. Send the schedule and any specification and we will give you a quote.
Signs you need new build mastic in Terriers
A new house holds a lot of water from the build, and it dries out over the first couple of years. As it does, timber shrinks and joints open and the sealant has to cope with the movement.
Common reasons people contact us are:
- Kitchen sealant that has pulled off the wall
- Second-fix sealing on new plots
- Cracks appearing as a new home settles
- Frame joints opening as the plaster dries
If you’ve bought a new home near High Wycombe station, the sealant around baths, showers and frames is worth checking in the first year or two.
