About our new build mastic in Eynsford
New homes move as they dry out. Timber shrinks, plaster dries and baths and trays bed down, so sealant that was laid quickly before handover often cracks. We work on plot handovers, skirting & floors and kitchens, and common reasons people get in touch are gaps between new skirting and floors and sealant work across a run of new homes.
Work in a small place like Eynsford just needs the journey and access planning, and once on site, the job is the same as anywhere.
There’s a 12-month guarantee on every job, large or small.

Common questions in Eynsford
Do you cover smaller places like Eynsford?
Yes, Eynsford is covered. We work across London and the South East, from towns to the smallest places. Longer journeys are simply planned in advance.
Do you work for landlords with property near Eynsford station?
Yes, landlords and agents are among the people we work for. Just call 0345 464 0079 or send us an email with the address and what needs doing, and we will give you a clear quote.
Do you have insurance?
Yes. We are fully insured for every job we do.
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.
Which products do you use?
We choose the sealant for the joint, not the other way round. Movement, water and weather all affect the choice.
Do you work for hotels and businesses?
Yes. We work in offices, washrooms, hotels and other commercial premises. Working times can be discussed when we quote.
What colour sealant will you use?
The colour is chosen to suit the tiles, worktop or frame. Let us know your preference when you ask for a quote.
Will you leave a mess?
Very little: the area around the joints is protected first, and we clear up the old sealant and our materials before we leave.
Joints and finishes in Eynsford homes
Rainfall in the South East is lower than in much of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
For new homes near Eynsford station, it’s worth checking the sealant early, while snags are still fresh.

Different surfaces, different methods
Kitchens
Worktop, upstand and sink joints in new kitchens often get a hurried bead. We take it out and reseal neatly, colour-matched where it shows.
Windows and doors
On new builds, external frame sealant can be patchy. It’s resealed with an exterior sealant suited to the frame and wall.
Can I do it myself?
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 fails, we can still redo it.
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
Do you need new build mastic in Eynsford?
Sealant applied onto damp surfaces doesn’t bond well. On a busy site, joints are not always given time to dry first.
Look out for these signs:
- Untidy sealant flagged on a snagging list
- Cracks appearing as a new home settles
- Cracked caulk along new skirting
- Kitchen sealant that has pulled off the wall
Around Eynsford, as everywhere, new build mastic is only as good as the preparation behind it.

Other services in Eynsford
Looking after it afterwards
Joint life depends on how it’s used and looked after. Here’s what we suggest:
- Keep water off fresh sealant until it has cured
- Record problems with dated photos
- Avoid scourers and strong chemicals on sealant
- Look at the sealant regularly in the first couple of years
Photograph failed sealant before it’s redone and keep the builder’s replies. It’s useful if you need to raise other issues later.
Lifting sealant traps moisture and mould behind it. Resealing before mould gets in keeps the job straightforward.
For landlords and businesses
Whether it’s one flat or a portfolio, the work is the same standard: the old material taken out, careful preparation and a 12-month guarantee.
We also work for property managers and facilities teams. We can quote a run of properties together, and we’re fully insured.
How the visit works
On the day, we start by going over the job with you, so you know exactly what we are doing. Surfaces next to the work are protected before we start. The work normally takes a few hours in a single home. Somewhere as small as Eynsford, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- First, the list of joints is agreed from your snagging sheet or plot schedule.
- The failed sealant is removed completely down to clean surfaces.
- 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.
How to prepare
- Try not to wet indoor joints just before the visit
- Keep children and pets away from the work area
- For business premises, tell us about site rules or sign-in
