Work for landlords, hotels and businesses
A neglected joint can let water reach the structure, which is a bigger problem in a rented property. Resealing at the right time is simple maintenance that we can handle for you.
We also work for businesses, from offices to washrooms and kitchens. On commercial sites, working times can be discussed when we quote.
About our new build mastic in Chorleywood West
We never seal over a failed new-build bead. New silicone will not bond to old silicone, so the joint is cut out, cleaned, dried and resealed. If you have gaps opening as the house dries out and settles and leaking shower tray seals in a new home, we can put it right, whatever the surface.
Around Chorleywood West, older homes often have timber floors that move through the year, so skirting and threshold joints need a flexible sealant rather than a rigid filler.
A 12-month guarantee comes as standard, so you’re covered after we have gone.

My new home is still under warranty. Should I contact you?

Can you quote for more than one area?
Yes. Tell us about everything you’d like done.
Is it normal for sealant to crack in a new home?
A new house dries and settles for a year or two, and sealant is often rushed onto dusty, unprimed surfaces. Either can make it fail early.

Advice
Leave it or put it right?
Small cosmetic gaps can wait for the house to settle, but a leaking seal can’t. Not sure whether yours can wait? You can ring 0345 464 0079 or drop us an email with a few pictures. Around Chorleywood West, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
The cost depends on the size of the job, how hard the old material is to remove and access to the work. We give a clear quote before any work starts, so you know where you stand.

Can I do it myself?
A DIY attempt doesn’t rule out a professional job. We cut it out and start again, so tell us about it when you ask for a quote.
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.

What we’re called out for in Chorleywood West
On many sites, sealant goes on in the final rush before handover. Dusty, unprimed joints are common, so the bead never bonds properly.
Most people get in touch when they notice one of these:
- Smeared, uneven beads picked up at snagging
- Gaps between new skirting and floors
- Kitchen sealant that has pulled off the wall
- Frame joints opening as the plaster dries
For new homes near Rickmansworth station, it’s worth checking the sealant early, while snags are still fresh.
