New-build mastic & snagging in Sayers Common, West Sussex
New-build sealant joints in Sayers Common need attention? We cut out the old, prepare the joints and apply the right sealant, and the work is guaranteed for a year.
- Gaps opening as the house dries out and settles
- Internal frame sealant that has split
- Beads laid onto grit and dust from the build
DIY versus a professional finish
Sealing over old silicone is the commonest DIY error. New silicone won’t bond to old, so it peels away and traps moisture behind it. Everything old must be removed first.
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
About our new build mastic in Sayers Common
New homes move as they dry out. Timber dries and shrinks, and baths and trays settle, so sealant that was laid quickly before handover often cracks. Common call-outs are for internal frame sealant that has split and gaps between new skirting and floors, across windows & doors, plot handovers and bathrooms & en suites.
Around Sayers Common, older homes often have timber floors that move through the year, which is why skirting and threshold joints need a flexible sealant, not filler.
All of our work is guaranteed for twelve months, and the guarantee is the same wherever you are.

Advice
What we are called out for in Sayers Common
Fresh sealant can be knocked or cut by trades finishing off. If it’s disturbed before curing, the joint can be left weak, and the problem shows up after you move in.
These are the problems we are asked about most:
- Plot mastic for developers ahead of handover
- Worktop and upstand sealant coming away
- Gaps between new skirting and floors
- Sealant that never bonded to the surface
If you’ve bought a new home near Hassocks station, the sealant around baths, showers and frames is worth checking in the first year or two.

Different surfaces, different methods
Skirting and floors
Floors and skirting move as the house dries and the heating runs. Caulk cracks; a flexible sealant moves with it painted or coloured to suit.
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.
For landlords and businesses
In hotels, rooms out of use cost money, so we plan the work room by room around your bookings where we can. We’ve worked in hotels as well as homes and businesses.
From a single let to a portfolio, the work is the same standard: the old material taken out, careful preparation and a 12-month guarantee.

Sayers Common questions
Is Sayers Common within the area you cover?
Yes, we do. Our work covers London and the South East, from towns to the smallest places. Longer journeys are simply planned in advance.
Can you help a landlord with a rental near Hassocks station?
Yes, we work for landlords and agents. You can call 0345 464 0079 or drop us an email with the address and a few details, and we’ll give you a fixed price before we start.
Will you just run a new bead over the existing one?
No. Over-sealing traps mould and water and soon fails. We remove every bit of the old bead before resealing.
My new home is still under warranty. Should I contact you?
Your builder, if you are still in their snagging or warranty period. If that doesn’t work out, we’re happy to quote and our work is guaranteed for a year.
What colour sealant will you use?
That depends on what the joint meets: white or clear for most sanitary joints, colours for worktops, floors and frames. We will agree it with you first.
Are you an approved applicator?
Yes. We’re approved under the ARBOMaster scheme, the approved applicator scheme for Arbo sealants.
Can I do it myself?
For a simple, easy-to-reach joint, a careful DIYer can do a reasonable job. Most DIY failures come from sealing over old material, wet joints or too much sealant.
Will it make a mess?
Tidy work is part of the job. Nearby surfaces are protected.
