Questions from East Hampnett
I let a flat near Barnham station. Can you help?
Yes, we work for landlords and agents. You can ring 0345 464 0079 or send us an email with the address and a few details, and we’ll give you a fixed price before any work starts.
Will you come out to East Hampnett?
Yes, East Hampnett is covered. We work across London and the South East, from towns to the smallest places. Longer journeys are simply planned in advance.
Can I send you my snagging list?
Yes. Photos of each sealant item help us quote. Items that need a plumber, tiler or the builder are flagged.
Are you ARBOMaster approved?
Yes. ARBOMaster is the approved applicator scheme for Arbo sealants, and we’re part of it.
How do I get a quote for new build mastic in East Hampnett?
It depends on the job, so we quote each one individually. To get one, call 0345 464 0079 or drop us an email and let us know what needs doing and where.
How long before the joint can be used?
Cure times vary by product and the conditions. Before we leave, we will tell you the cure time.
What sealant do you use?
The product depends on the job: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. Brands we use include Arbo and Everbuild.
Do you work for developers?
Yes. Second-fix sealing in bathrooms, kitchens, frames and floors is part of what we do. We clean and prime joints properly to keep callbacks down.
How we handle new build mastic in East Hampnett
Failed shower seals, gaps along the skirting and messy beads are common items on a new-home snagging list. While the builder’s snagging or warranty period runs, report it to them first. We work on skirting & floors, plot handovers and windows & doors, and the jobs we see most are sealant that never bonded to the surface and gaps behind new kitchen upstands.
Older homes in small places like East Hampnett often have timber floors that move with the seasons, so skirting and threshold joints need a flexible sealant rather than a rigid filler.
There’s a 12-month guarantee on every job, whatever its size.

Landlord and commercial work in East Hampnett
Housing providers, facilities teams and property managers book us too in East Hampnett and across West Sussex. Several sites can go on one quote, and we’re fully insured.
We also work for businesses, from offices to washrooms and kitchens. For commercial premises, we can talk through working times when we quote.
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:
- Broken tiles or a split tray
- Structural cracks in walls or ceilings
- Your warranty claim itself, which is between you and the builder
If in doubt, ring 0345 464 0079 or email us and we will say what we think before you book.
Surfaces we seal
- Skirting & floors
- Kitchens
- Bathrooms & en suites
- Plot handovers
- Show homes
- Windows & doors
Looking after it afterwards
A little care helps the new joints last. Our advice:
- Keep pictures and emails about snagging items
- Put sealant faults on your snagging list early
- Use the extractor fan every time you shower
- Wipe joints with warm soapy water
Photograph failed sealant before it’s redone and keep the builder’s replies. It’s useful if you need to raise other issues later.
Early snagging is easier snagging. Left alone, a small crack can become a leak over time.

What else we do in East Hampnett
DIY versus a professional finish
A DIY attempt does not rule out a professional job. We cut it out and start again, so just mention it when you contact us.
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
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.
Bathrooms and en suites
Baths, showers, basins and trays in new bathrooms are the most common new-build reseal. We cut out the failed bead, clean and prime, and reseal with anti-fungal sanitary silicone.
New build mastic in East Hampnett: local notes
