New Build Mastic in Hightown
Our applicators work in Hightown on plot mastic for developers and snagging failed sealant in new homes. Old sealant removed completely, joints prepared properly and a 12-month guarantee.
- Smeared, uneven beads picked up at snagging
- Sealant applied over dusty or wet surfaces
- Shower seals failing in the first year or two
New build mastic in Hightown, done properly
In a new home, every joint should have a clean, even bead. When the finish is smeared, patchy or already cracking, it’s worth putting right early, before water gets into the floor or walls. If you are dealing with cracks appearing as a new home settles and worktop and upstand sealant coming away, we can put it right, whatever the surface.
Older homes in small places like Hightown often have timber floors that move with the seasons, which is why skirting and threshold joints need a flexible sealant, not filler.
Whatever the size of the job, it’s backed by our 12-month guarantee.

Why deal with it now?
The builder is generally the first port of call while the snagging or warranty period runs. If it keeps failing or isn’t dealt with, we can reseal it properly. In a small place like Hightown, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
A few things move the cost up or down: the old material and how easily it comes out, any mould to treat, and whether the work is at height. Your quote takes all of that into account.
What you get with us
- Colour agreed with you before any work starts
- Neat joints and a tidy finish
- Any old sealant cut out fully, not covered over
- 20+ years of sealant experience

What information do you need?
Where the job is, what the problem is and roughly how big it is. If you can, email a few pictures.
Keeping the joints in good condition
Good habits help new joints last longer. Our tips:
- Follow the cure time we give you
- Clean sealant with mild detergent, not abrasives
- Check bath and shower seals every few months as the house settles
- Open a window or run the fan after bathing
Avoid standing on the rim of the bath or the edge of the tray while the sealant cures. Report any movement in a bath or tray.
Do not let the snagging period run out with sealant problems unreported. After that, putting it right may fall to you.
Landlord and commercial work in Hightown
Water getting past a failed joint can damage the building, which is a bigger problem in a rented property. Keeping joints in good order is simple maintenance that we can handle for you.
We regularly work with letting and managing agents. Tell us the address, the job and how access works and we’ll quote.
How it works
Before we leave, we go over the finished joints with you. The visit itself normally takes anything from a few hours to several days, depending on the number of plots, depending on how much there is to do. In a small place like Hightown, access is generally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We go through the snagging list or plot schedule and agree the joints to do.
- We cut out every bit of the failed or messy sealant.
- Each joint is cleaned of dust and grit, then primed if required.
- A sealant chosen for each area goes in and is tooled smooth.
- Finally, each room is checked and you are given the cure time.
How to prepare
- Mention any sign-in or site rules at work premises
- Keep children and pets away from the work area
- Mention any tricky access

Advice
When to call us in Hightown
When the heating goes on in the first winter, the house dries fast. Gaps open along skirting, frames and worktops and cracks appear in the sealant.
Signs it’s time to call us include:
- Worktop and upstand sealant coming away
- Cracks appearing as a new home settles
- Messy sealant that spoils new finishes
- Plot mastic for developers ahead of handover
Whether the job is in Hightown itself or nearby, the right material for each joint matters as much as a neat finish.
Before booking anyone
- How the joint is cleaned and prepared
- How long to leave it before use
- Whether they seal over old material or remove it
- What guarantee comes with the work
What we can’t put right
Some problems need a builder, plumber or other trade rather than us:
- Leaks from pipes, valves or wastes, which need a plumber
- Cracking that points to a structural problem
- Cracked trays, tiles or worktops
If in doubt, ring 0345 464 0079 or email us and we will say what we think.
