New build mastic in East Horndon
Some owners wait for the first year’s movement before having joints redone. For small cosmetic gaps, that’s reasonable, but a seal that is letting water through needs doing now. We work on kitchens, skirting & floors and bathrooms & en suites, and people most often call us about internal frame sealant that has split and sealant applied over dusty or wet surfaces.
Work in a small place like East Horndon just needs the journey and access planning, and once on site, the job is the same as anywhere.
Big or small, you get the same 12-month guarantee in East Horndon and across Essex.

Work for landlords, hotels and businesses
Businesses can book us for washrooms, kitchens, offices and more. On commercial sites, working times can be discussed when we quote.
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 that we can handle for you.
How the job changes by surface
Skirting and floors
Wet-area floor joints need a flexible seal. They get a flexible, water-resistant sealant.
Bathrooms and en suites
Baths, showers, basins and trays in new bathrooms are the most common new-build reseal. We cut out the failed bead, clean and prime, and reseal with anti-fungal sanitary silicone.

The work is kept neat and contained to the area we’re working on, so you can carry on as normal. The job normally takes a few hours in a single home.

Advice
How to look after the new joints
Joint life depends on how it’s used and looked after. We suggest:
- Ventilate bathrooms well, especially in the first year
- Record problems with dated photos
- Follow the cure time we give you
- Get a leaking seal dealt with right away
Photograph failed sealant before it’s redone and keep the builder’s replies. It helps if anything else comes up during the warranty period.
Report failed sealant to the builder while you are in the snagging period. After that, putting it right may fall to you so report it promptly.
Questions from East Horndon
I let a flat near West Horndon station. Can you help?
Yes, we work for landlords and letting agents. You can call 0345 464 0079 or send us an email with the address and a few details, and we’ll give you a fixed price before work begins.
Can you do new build mastic in East Horndon?
Yes, East Horndon is within the area we cover. We work across London and the South East. Just phone 0345 464 0079 or send us an email with a few details of the job.
What should I tell you?
Just the basics: where it is, what you’ve noticed and how we reach it. Then phone 0345 464 0079 or send us an email.
How long before the joint can be used?
Many sealants skin over quickly but take longer to cure fully. We’ll give you the cure time for the product we used before we leave.
How long does new build mastic take?
As a guide, most jobs take a few hours in a single home. Larger jobs naturally take longer, and we will tell you how long to expect.
Are you ARBOMaster approved?
Yes. We’re ARBOMaster approved, the scheme for applicators of Arbo sealants.
Will you just run a new bead over the existing one?
No. Fresh silicone does not stick to the old layer, so sealing over the top fails quickly. The old sealant always comes out first.
My new home is still under warranty. Should I contact you?
Report it to the builder first while you are covered. Once that’s done, or if they won’t put it right, we can reseal it properly.
Why deal with it now?
A failed shower or bath seal in a new home lets water into floors and walls that are still drying out. Dealing with it early keeps the damage away from ceilings, floors and finishes. Where a wall is exposed, as many are in small places like East Horndon, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
Instead of a standard rate, we price the job in front of us: the amount of work, the old material and the access. You will know the price before we begin.

Should I try it myself first?
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 do try it yourself, take your time over the 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.
