How we handle new build mastic in Labour-in-vain
Snagging sealant properly means taking the failed bead out completely. New silicone won’t bond to old silicone, so the joint is cut out, cleaned, dried and resealed. Typical jobs include cracked sealant around new window and door frames and kitchen sealant that has pulled off the wall, across bathrooms & en suites, skirting & floors and kitchens.
Older homes in small places like Labour-in-vain 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 covered for a year after we finish. If anything is not right with it, ring 0345 464 0079 or send us an email.

Can I do it myself?
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
If you’re set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.
How the job changes by surface

We can refresh show-home sealant that has discoloured or been knocked. We cut it out and reseal neatly.

New-build bathrooms and en suites are where sealant fails most often. We cut out the failed bead, clean and prime, and reseal with anti-fungal sanitary silicone.
Quotes for new build mastic in Labour-in-vain
There’s no set price list. The quote depends on:
- Which sealant suits the joint
- When we can work, for business premises

Before you ask for a quote, have a think about:
- Pictures of the joints, sent by email

Landlord and commercial work in Labour-in-vain
Whether it’s one flat or 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.
Leave it or put it right?
Resealing everything on a snagging list in one visit is usually simpler than chasing joints one at a time. You get one visit and one clear quote for the lot. Around Labour-in-vain, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
Instead of a standard rate, we price the job in front of us: the amount of work, the old material and the access. You’ll know the price before we begin.
Why book with us
- An ARBOMaster approved applicator
- A 12-month guarantee on all work

New homes and floors in Labour-in-vain

Around Labour-in-vain, as everywhere, new build mastic is only as good as the preparation behind it. If you’ve bought a new home near Borough Green & Wrotham station, the sealant around baths, showers and frames is worth checking in the first year or two.

Looking after it afterwards
So the new joints stay in good condition:
- Avoid scourers and strong chemicals on sealant
- Ventilate bathrooms well, especially in the first year
- Follow the cure time we give you
- Get a leaking seal dealt with right away
Leave the sealant for the cure time we give you before showering or bathing. Most silicones need around a day to cure enough for use.
A failed seal in a new home lets water into joists, plasterboard and ceilings. Early resealing keeps the job small and the new finishes intact.
How it works
When we arrive, we look over the joints with you first, so you know exactly what we are doing. We protect the surfaces around the joints before any work begins. Most jobs take anything from a few hours to several days, depending on the number of plots. For a village or hamlet like Labour-in-vain, 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.
- First, the list of joints is agreed from your snagging sheet or plot schedule.
- Every bit of the old builder’s sealant is cut out.
- 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.
Before we arrive

- Tell us about access, such as stairs, a lift or high-level joints
