DIY versus a professional finish
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
If you’ve already had a go yourself, that is fine. We remove it and do the joint properly.
New build mastic in Wiston
Failed shower seals, gaps along the skirting and messy beads are common items on a new-home snagging list. If you’re still within the builder’s snagging or warranty period, tell them first and if that stalls, we can do it. Typical jobs include frame joints opening as the plaster dries and cracked caulk along new skirting, on bathrooms & en suites, show homes and kitchens.
Older homes in small places like Wiston often have timber floors that move with the seasons, so skirting and threshold joints need a flexible sealant rather than a rigid filler.
The work is guaranteed for twelve months. If something isn’t right with it in that time, tell us and we will put it right.

Aftercare tips
After the cure time, these simple habits help:
- Avoid running a DIY bead over the old one
- Watch for new gaps as the house dries out
- Put sealant faults on your snagging list early
- Keep pictures and emails about snagging items
Clean the sealant with a mild detergent and a soft cloth. Keep scourers and harsh chemicals off it.
If a shower tray or bath seal splits in the first year, look for movement. Getting it resealed properly, and any movement checked, stops it recurring.

How the job changes by surface
Windows and doors
Draughts around new frames are often a sealant gap. We look at the joints and reseal where needed.
Skirting and floors
New homes often develop a gap between skirting and floor. A flexible sealant closes it without cracking like caulk.
Why act early in Wiston
Small cosmetic gaps can wait for the house to settle, but a leaking seal cannot. Not sure whether yours can wait? You can ring 0345 464 0079 or email us with a few photos. Where a wall is exposed, as many are in small places like Wiston, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
No two jobs are quite the same, so we quote each one individually. The number of joints, how easy they are to reach and the sealant needed all play a part.
Why book with us
- Sanitary silicone with an anti-fungal additive in wet areas
- Rated 4.9 stars on Google
- Old sealant always removed completely
- One-year guarantee on every job

Wiston: your questions answered
Is new build mastic in Wiston guaranteed?
Every job comes with our 12-month guarantee, wherever it is. We’re fully insured, and an ARBOMaster approved applicator.
Will you come out to Wiston?
Yes, smaller places are covered as well as towns. We work across London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Does someone need to be in?
For indoor joints, yes, someone needs to let us in. Once we have agreed the job, you don’t need to watch us work.
Do the sealants smell?
Possibly a little. Any smell clears as the sealant cures.
Do you hold any approvals?
Yes. We are approved under the ARBOMaster scheme, which is run for the Arbo sealant brand.
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.
I’m a tenant. Can you help?
We’re happy to deal with the tenant, landlord or agent. Get your landlord’s agreement first.
Can you match the sealant colour to my new kitchen or bathroom?
Most bathroom joints are white or clear, but sealant comes in other colours too. We choose one to suit the room.
How it works
We work through the job in order: protect, prepare, seal, tidy. For most jobs that takes a few hours for most snagging lists, longer for a run of plots. In a small place like Wiston, access is normally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We start by going through the snagging items or plot schedule with you.
- The failed sealant is removed completely down to clean surfaces.
- We clean out the dust and grit left from the build.
- 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.
Preparing for the visit
- Let us know about stairs, lifts or work at height
- For business premises, tell us about site rules or sign-in
- Move anything stored near the joints
Get a quote
Getting a quote is simple: let us know what needs doing and where, and roughly how big it is. A few pictures by email make the job easier to understand, and we will take it from there.
Advice
Honest limits
New sealant can’t fix everything, and we will tell you before we start. Sealant will not put right:
- Movement caused by a poorly fitted tray or bath
- Disputes or warranty claims with your builder
- Settlement cracks that need a surveyor
If you are not sure, just call 0345 464 0079 or send us an email and we’ll give you a straight answer before you book.
