New build mastic in Furner's Green
Building dust is behind a lot of failed new-build sealant. Each joint is cleaned of dust and primed where the product calls for it, so the sealant actually sticks instead of bonding to the dust. If you’re dealing with second-fix sealing on new plots and skirting joints opening in the first winter, we can help, on skirting & floors, plot handovers and windows & doors alike.
Somewhere as small as Furner's Green, new homes tend to be conversions, self-builds or a few houses rather than an estate. Every one needs its sealant and floor joints done properly, whatever the size of the site.
All our work is covered by a one-year guarantee, wherever you are in East Sussex.

Common questions in Furner's Green
Do you work for landlords with property near Haywards Heath station?
Yes, landlords and agents are among the people we work for. Just ring 0345 464 0079 or drop us an email with the address and what needs doing, and we’ll send you a clear quote.
Do you cover Furner's Green for new build mastic?
Yes. Our work covers London and the South East, and Furner's Green is part of that. Just phone 0345 464 0079 or email us with a few details of the job, and we’ll send you a clear quote.
Is there a guarantee?
Yes, always. There’s a 12-month guarantee on every job, large or small.
Should I go to my builder first?
If you’re still within the builder’s snagging or warranty period, report it to them first. If they’re slow or the fix does not last, we can help.
Do you work through snagging lists?
Yes. Send us the sealant items on the list, with photos if you can and we will give you a quote. We’ll tell you if anything on it is not a sealant job.
Do the sealants smell?
Possibly a little. It fades as the sealant cures, and ventilation helps.
When is the best time to reseal in a new build?
Any seal that’s leaking should be redone right away. Cosmetic gaps can wait until the first year or two of movement has passed.
Are you ARBOMaster approved?
Yes. Mr Mastic is an ARBOMaster approved applicator, and we are fully insured.
How the visit works
When we get to you, we compare the joints with what we discussed. If we find something unexpected, we talk it through with you first. After that, the work takes anything from a few hours to several days, depending on the number of plots. For a village or hamlet like Furner's Green, the journey is planned in advance: let us know about lanes, gates and parking. We bring what the job needs, so it can be finished in one trip where possible.
- We look at why each joint failed, including any movement.
- Old sealant is cut out and the joints cleaned.
- We make sure the joints are dry and prime them if needed.
- New sealant goes in, with baths filled first so they’re at their heaviest.
- The finished joints are checked and the cure times given.
Preparing for the visit
- Move anything stored near the joints
- Where the joints are inside, avoid wetting them before we arrive
- Mention any tricky access

Advice
Looking after it afterwards
Once the sealant has cured, a few habits help it last:
- Clean sealant with mild detergent, not abrasives
- Avoid running a DIY bead over the old one
- Put sealant faults on your snagging list early
- Watch for new gaps as the house dries out
Keep the bathroom ventilated, especially in the first year. Run the fan or open a window after bathing to help keep mould away.
A seal that splits early is often a sign of movement. Have it resealed, and the tray or bath checked, before it gets worse.
What we are called out for in Furner's Green
New homes are full of moisture from plaster, screed and concrete, which takes a year or two to dry out. Drying timber shrinks and pulls joints apart.
Common reasons people contact us include:
- Joints pulling apart as timber shrinks
- Cracked sealant around new window and door frames
- Sealant that never bonded to the surface
- Second-fix sealing on new plots
In and around Furner's Green, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.

- Who turns up on the day
- Whether they’re fully insured
- How the surfaces are prepared before sealing

- Where the property is
- The type of property
- How many joints, rooms or windows are involved
- Access, such as stairs, a lift or height

Work for landlords, hotels and businesses
From a single let to a portfolio, you get the same standard of work: the old material taken out, careful preparation and a 12-month guarantee.
A neglected joint can let water reach the structure, which is a bigger problem in a rented property. Resealing at the right time is simple maintenance that we can handle for you.
Should I try it myself first?
Sealing over old silicone is the commonest DIY error. Silicone doesn’t stick to old silicone, so it peels away and traps moisture behind it. All the old material has to come out first.
If you’re set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it doesn’t work out, we can still put it right.
