New build mastic for homes and businesses in Benson
Some owners wait for the first year’s movement before having joints redone. That makes sense for small gaps that are just cosmetic, but a seal that is letting water through needs doing now. If you have frame joints opening as the plaster dries and smeared, uneven beads picked up at snagging, we can put it right, whatever the surface.
For a new home in or near Benson, it’s worth checking the sealant early. Common snags include open skirting joints, lifting shower seals and gaps around frames.
A one-year guarantee comes with the work, just as it does everywhere we cover.

DIY sealant or a professional job?
The biggest DIY mistake is sealing over old sealant. Silicone does not stick to old silicone, so it peels away and traps moisture behind it. All the old material has to come out first.
If you’ve already had a go yourself, that is fine. We remove it and do the joint properly.

How long does the job take?
Most jobs take a few hours in a single home. We’ll confirm how long when we quote.
Do you work for hotels and businesses?
Yes. Commercial and hotel work is a large part of what we do. We can talk about working times when we quote.
Should I wait before resealing?
For failed seals that let water through, the best time is now. Cosmetic gaps can wait until the first year or two of movement has passed.

Yes. Just list everything you need and you will get one quote.
What colour sealant will you use?
It depends on the joint: white or clear for most sanitary joints, colours for worktops, floors and frames. We’ll agree it with you first.
Looking after it afterwards
Good habits help new joints last longer. Our tips:
- Open a window or run the fan after bathing
- Keep pictures and emails about snagging items
- Keep water off fresh sealant until it has cured
- Report sealant problems to your builder during the snagging period
Clean the sealant with a mild detergent and a soft cloth. Avoid abrasive pads and strong solvents, which can damage the surface.
A failed seal in a new home lets water into joists, plasterboard and ceilings. Early resealing keeps the job small and the new finishes intact.

When something else is needed
We’d rather tell you now than do work that will not last, so here’s what sealant cannot put right:
- Movement caused by a poorly fitted tray or bath
- Settlement cracks that need a surveyor
- Plumbing faults behind the sealant
If in doubt, phone 0345 464 0079 or drop us an email and we’ll say what we think.
Joints and surfaces we work on
- Plot handovers
- Skirting & floors
- Bathrooms & en suites
- Kitchens
- Show homes
- Windows & doors
Why it’s worth doing now in Benson
Water getting past a failed seal in a new build reaches walls and floors that are still settling. Dealing with it early keeps the damage away from ceilings, floors and finishes. In an older home around Benson, damp from a failed joint can get into timber and plaster, and that is a much bigger job than renewing the sealant.
A failed joint rarely gets cheaper to fix by waiting. If you are unsure, ring 0345 464 0079 or email us and we will give you an honest view and a quote.
