New build mastic for homes and businesses in Batford
Dust is the enemy of new-build sealant. Each joint is cleaned of dust and primed where the product calls for it, so the new bead bonds properly instead of bonding to the dust. Typical jobs include skirting joints opening in the first winter and internal frame sealant that has split, on windows & doors, show homes and bathrooms & en suites.
In smaller places like Batford, new homes tend to come as small developments or single plots. Each still needs its sealant and floor joints finished properly from day one.
We stand behind the work with a 12-month guarantee, so you’re covered after we’ve gone.

Your questions about new build mastic in Batford
Do you cover smaller places like Batford?

Is Batford in your area for new build mastic?

Where do you work from?
Our base is in Crawley, and we cover South East England, London and all of Scotland.
Can tenants book the work?
Yes. Ask your landlord first, and we can send them the quote if that helps.
What sealant do you use?
Each joint gets the product that suits it. Where it moves, gets wet or faces the weather makes a difference, and we’ll tell you what we are using.
What colour sealant will you use?
White and clear are the most common, but sealant comes in other colours too. We choose one to suit the room before we begin.
Do you work for landlords and businesses?
Yes, often. Several properties can go on one quote, and between tenancies is a good time for the work.
Do you remove the old sealant?
Yes. All of the old material is cut out and the joint cleaned before resealing.
DIY versus a professional finish
If you’ve already had a go yourself, that is fine. We cut it out and start again, so tell us about it when you ask for a quote.
Sealing over old silicone is the commonest DIY error. Silicone does not stick to old silicone, so it peels away and traps moisture behind it. All the old material has to come out first.
What sealant work cannot fix
We’d rather tell you now than do work that will not last, so these are the limits:
- Leaks from pipes, valves or wastes, which need a plumber
- Cracked trays, tiles or worktops
- Deciding who is responsible under a builder’s warranty
If you are not sure, just call 0345 464 0079 or send us an email and we’ll give you a straight answer before booking.

Landlord and commercial work in Batford
Water getting past a failed joint can damage the building, which matters even more when someone else lives there. Keeping joints in good order is simple maintenance.
We also work for businesses, from offices to washrooms and kitchens. On commercial sites, working times can be discussed when we quote.
Common problems we fix in Batford
If plaster or screed was still damp when it was sealed, the bond suffers. On a busy site, joints are not always given time to dry first.
The most common problems we see are:
- Untidy sealant flagged on a snagging list
- Gaps between new skirting and floors
- Worktop and upstand sealant coming away
- Cracked sealant around new window and door frames
In and around Batford, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.
Questions to ask before booking
- Are they insured?
- Is VAT in the price?
- Is the old sealant removed completely?
- Whether the sealant suits the joint
The process
You do not need to clear the whole room or building, only the area right around the joints. We protect the rest, and the work takes a few hours in a single home in most cases. Parking around Batford is normally easier than in a town centre, but mention any lanes, gates or long drives. If the job is outside, tell us about side access and how high the joints are.
- We look at why each joint failed, including any movement.
- We remove the failed sealant and clean the joints.
- We make sure the joints are dry and prime them if needed.
- Baths are filled with water, then the new sealant is applied.
- The finished joints are checked and the cure times given.
Getting ready for the visit
- Tell us about access, such as stairs, a lift or high-level joints
- Try not to wet indoor joints just before the visit
- Keep pets and children clear of the area while we work

Why it’s worth doing now in Batford
A quick bead over the top of the old sealant can look fine at first, but it will not bond to the old layer. A lasting seal starts with removing the old one completely. Around Batford, water from a failed joint in an older home can soak into timber and plaster, which is far harder to put right than the sealant itself.
Some things make a job bigger or smaller: how much old sealant there is and how stubborn it is, any mould to treat, and whether the work is at height. Your quote takes all of that into account.
