Homes and businesses are quoted the same way: how much there is to do, how we reach it and what it needs, plus any working-time requirements on site. Ask us for a quote and we will explain what it covers.

How it works
Our applicators work methodically: protection first, then preparation, sealing and a tidy-up. Typically it takes anything from a few hours to several days, depending on the number of plots. Somewhere like West Horndon needs a little journey planning: tell us about narrow lanes, gates, long drives and where we can park. Everything for the job comes with us, so a second trip is avoided 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, with no layer left behind.
- We clean out the dust and grit left from the build.
- We prime where needed and apply a sealant suited to each joint.
- Each bead is tooled and the cure times explained.
Getting ready for the visit

FAQs for West Horndon
Is West Horndon in your area for new build mastic?
Yes. We work across London and the South East, and West Horndon is part of that. Just call 0345 464 0079 or email us with a few details of the job, and we will give you a clear price.
Do you cover smaller places like West Horndon?
Yes, West Horndon is covered. Our work covers London and the South East, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
Do you remove the old sealant?
Yes, every time. New sealant won’t bond properly to old, so any old material comes out before anything new goes in.
What does new build mastic cost?
We don’t publish prices, because the cost depends on the job: its size, the old material, access and the product needed. We agree the price before any work begins.
What colour sealant will you use?
It depends on the joint: white or clear for most sanitary joints, colours for worktops, floors and frames. We’ll agree it with you first.
Are you an approved applicator?
Yes. We are approved under the ARBOMaster scheme.
Can I do it myself?
It depends on the job. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional, while a short indoor joint may be within reach.
Should I go to my builder first?
If you are still within the builder’s snagging or warranty period, report it to them first. If they’re slow or the fix doesn’t last, we can help.

What sealant work cannot fix

- Settlement cracks that need a surveyor
- Your warranty claim itself, which is between you and the builder
- Broken tiles or a split tray
Not sure which it is? You can call 0345 464 0079 or send us an email and we will tell you honestly before you book.

DIY sealant or a professional job?
If you do try it yourself, take your time over the 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.
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
What we are called out for in West Horndon
A new house holds a lot of water from the build, and it dries out over the first couple of years. Drying timber shrinks and pulls joints apart and the sealant has to cope with the movement.
People generally contact us after spotting something like this:
- Joints pulling apart as timber shrinks
- Cracked sealant around new window and door frames
- Gaps behind new kitchen upstands
- Sealant work across a run of new homes
If you’ve bought a new home near West Horndon station, the sealant around baths, showers and frames is worth checking in the first year or two.
Questions to ask before booking
- Whether all the old sealant comes out first
- What the cure time is
- Whether VAT is included
- Which colour the sealant will be
What the job involves on each surface
Windows and doors
The gap between a new frame and its plaster reveal often opens up. We remove cracked sealant and apply a flexible one in a matching colour.
Plot handovers
Taking time over preparation reduces return visits. We clean out building dust before sealing and prime where the product needs it.
