New build mastic in Dorking
A new build should have a neat, sound bead at every joint. Smeared, patchy or cracked sealant is worth sorting early, before water reaches anything behind it. We work on bathrooms & en suites, kitchens and skirting & floors, and people most often call us about sealant work across a run of new homes and sealant that never bonded to the surface.
Towns like Dorking have older streets and newer estates side by side. In a newer home, sealant and floor joints are usually among the first things to need attention.
All our work comes with our one-year guarantee, wherever you are in Surrey.

Common problems we fix in Dorking
Later trades and the final clean can damage fresh sealant. A bead disturbed before it has cured may never seal properly.
Most people get in touch after spotting something like this:
- Cracked sealant around new window and door frames
- Gaps opening as the house dries out and settles
- Sealant applied over dusty or wet surfaces
- Shower seals failing in the first year or two
In and around Dorking, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.
What your quote should include
- Whether all the old sealant comes out first
- How the colour is chosen
- How the joint is cleaned and prepared
- How much experience the applicator has
Different surfaces, different methods
Kitchens
New-kitchen sealant is often applied in a rush. We take it out and reseal neatly, colour-matched where it shows.
Show homes
Tired or marked sealant in a show home can be renewed. The old bead comes out and a clean new one goes in.
Honest limits
In fairness, some problems need a different trade:
- Cracked trays, tiles or worktops
- A tray or bath that isn’t properly supported, until it’s fixed
- Disputes or warranty claims with your builder

What happens on the day
You don’t need to clear the whole room or building before we come, just the space around the work. We protect the rest, and the work takes a few hours for most snagging lists, longer for a run of plots for a typical job. In Dorking, parking is rarely complicated, though it helps to know about driveways or restrictions, and let us know if the work is upstairs, in a flat or up high outside.
- First, the list of joints is agreed from your snagging sheet or plot schedule.
- Every bit of the old builder’s sealant is cut out down to clean surfaces.
- Joints are vacuumed and cleaned of building dust.
- We prime where needed and apply a sealant suited to each joint.
- We tool every joint neatly and tell you when each area can be used.
Before we arrive
- Try not to wet indoor joints just before the visit
- Mention any parking rules near the property
- Tell us about any water getting in

Dorking: your questions answered
What guarantee comes with new build mastic in Dorking?
All our work, in Dorking and everywhere else, comes with a 12-month guarantee. We are also fully insured and ARBOMaster approved.
Can you do new build mastic in Dorking?
Yes, Dorking is within the area we cover. Our work covers London and the South East. Just call 0345 464 0079 or send us an email with a few details of the job, and we’ll give you a clear quote.
What information do you need?
The location, the problem and the rough size of the job. Photos by email help too.
Will it make a mess?
Not at all. The area is protected while we work and cleaned up afterwards.
Is it worth resealing while the house is still settling?
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.
Do you work for letting agents?
Yes, we do. Domestic, commercial and hotel work are all part of what we do.
Does someone need to be in?
That depends on where the joints are. For work indoors, someone needs to let us in, while outside work can sometimes be arranged differently.
Can you work from my snagging list?
Yes. Snagging lists are a common starting point for us. We agree the sealant items with you before we start.
How to look after the new joints
So the new joints stay in good condition:
- Record problems with dated pictures
- Raise failed sealant with the developer while you are covered
- Act quickly if a seal starts to leak
- Use the extractor fan every time you shower
Watch the joints as the house settles. Small gaps can appear as the house dries, and they’re simple to reseal once movement has slowed.
A seal that splits early is often a sign of movement. Have it resealed, and the tray or bath checked, before it gets worse.
For landlords and businesses
In hotels, rooms out of use cost money, so we plan the work room by room. We’ve worked in hotels as well as homes and businesses.
We also work for businesses, from offices to washrooms and kitchens. For commercial premises, we can talk through working times when we quote.

Should I try it myself first?
A DIY attempt doesn’t rule out a professional job. We remove it and do the joint properly, so just mention it when you contact us.
If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.
