Landlord and commercial work in Neithrop
A neglected joint can let water reach the structure, which is a bigger problem in a rented property. Keeping joints in good order is simple maintenance that we can handle for you.
In hotels, rooms out of use cost money, so the work can be planned room by room. Hotel work is part of what we do, alongside homes and businesses.
How we handle new build mastic in Neithrop
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 failed shower or bath seal shouldn’t wait. Common call-outs are for internal frame sealant that has split and cracked caulk along new skirting, across skirting & floors, plot handovers and windows & doors.
In and around Neithrop, floors range from older timber boards to tiles and newer finishes, from timber that moves with the seasons to tiles laid on concrete. The sealant at skirtings and thresholds has to suit the floor it meets.
You get a one-year guarantee, the same in Neithrop as everywhere else we work.

Common problems we fix in Neithrop
Sealant is often one of the last jobs before handover. Joints aren’t always cleaned of dust or primed, and the sealant sits on grit instead of the surface.
The most common problems we see are:
- New-build shower sealant that has already split
- Sealant applied over dusty or wet surfaces
- Frame joints opening as the plaster dries
- Worktop and upstand sealant coming away
In and around Neithrop, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.

Other services in Neithrop
What the job involves on each surface
Kitchens
Beside the sink, the joint takes water every day. We use a sealant suited to kitchens, food-safe where it’s needed.
Show homes
Show homes need sealant that looks right from day one. Every bead is neat and coloured to suit the room.
What happens if it’s left?
The builder is normally the first port of call while the snagging or warranty period runs. If it keeps failing or is not dealt with, we can reseal it properly. Homes in smaller places like Neithrop can face more weather, and failed outside joints let damp into walls. Indoors, a failed seal lets water into floors and panels as it would anywhere.
There are no prices on our website, because each job is priced on what it involves. Call for a quick quote.

FAQs for Neithrop
Can you do new build mastic in Neithrop?
Yes. We work across London and the South East, and Neithrop is part of that. You can phone 0345 464 0079 or drop us an email and tell us what needs doing, and we will give you a clear quote.
I let a flat near Banbury station. Can you help?
Yes, landlords and agents are among the people we work for, and several properties can be quoted together. You can phone 0345 464 0079 or email us with the details for a clear quote.
Can I do it myself?
Sometimes. The key is preparation: remove all the old material and work on a clean, dry joint. We can always put it right if it fails.
Is there a guarantee?
Yes: twelve months. If there’s a problem with our work in that time, tell us and we will put it right.
How do I get a quote for new build mastic in Neithrop?
It depends on the job, so we quote each one individually. To get one, phone 0345 464 0079 or send us an email with a short description of the job.
Can new sealant go on top of the old bead?
No. Over-sealing traps mould and water and soon fails. All the old sealant comes out before work begins.
What do you put in the joint?
The product depends on the job: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. We use products from Arbo and Everbuild.
Is it messy?
Tidy work is part of the job. We protect what’s around the joints, and the area is left clean when we finish.

What sealant work can’t fix
Sealant is not the answer to every problem, and we’d rather say so up front. Sealant will not put right:
- Leaks from pipes, valves or wastes, which need a plumber
- Baths and trays that move too much for sealant to cope with
- Disputes or warranty claims with your builder
Not sure which it is? You can phone 0345 464 0079 or send us an email and we will tell you honestly.
