For landlords and businesses
We work for letting agents and landlords as well as homeowners. Sealant work between tenants is a simple way to keep a property in good order.
Mouldy or split sealant often shows up at the end of a tenancy, and it’s easy to sort out between tenants. Several properties can be quoted together.
New build mastic for homes and businesses in Navestock Common
Developers send us the plot schedule and we work through it. Bathrooms, en suites, kitchens, frames and skirting are sealed ready for handover. If you have skirting joints opening in the first winter and kitchen sealant that has pulled off the wall, we can help, on windows & doors, bathrooms & en suites and show homes alike.
Older homes in small places like Navestock Common often have timber floors that move with the seasons, so skirting and threshold joints need a flexible sealant rather than a rigid filler.
All our work comes with our 12-month guarantee, wherever you are in Essex.

Keeping the joints in good condition
Once the sealant has cured, a few habits help it last:
- Resist patching a failed seal with a tube from the DIY shop
- Use the extractor fan every time you shower
- Watch for new gaps as the house dries out
- Report sealant problems to your builder during the snagging period
Keep an eye on the joints over the first couple of years. Small gaps can appear as the house dries.
A seal that splits early is often a sign of movement. Have it resealed, and the tray or bath checked, before it gets worse.
When something else is needed
Before booking, it’s worth knowing the limits too:
- Plumbing faults behind the sealant
- Deciding who is responsible under a builder’s warranty
- Movement caused by a poorly fitted tray or bath

FAQs for Navestock Common
Will you come out to Navestock Common?
Yes, Navestock Common is covered. We work across London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.
Do you work for landlords with property near Harold Wood station?
Yes, rental work is part of what we do. You can phone 0345 464 0079 or drop us an email with the address and a few details, and we’ll give you a fixed price before any work starts.
How long does new build mastic take?
That depends on how much there is to do, but as a guide it takes a few hours for most snagging lists, longer for a run of plots. We’ll tell you when we quote.
What do you need from me for a quote?
Just the basics: where it is, what you’ve noticed and how we reach it. Then ring 0345 464 0079 or email us.
When is the best time to reseal in a new build?
That depends on the joint. A leaking shower or bath seal should be redone right away, but cosmetic gaps can wait for movement to slow.
Can I do it myself?
You can, for simple jobs. The key is preparation: remove all the old material and work on a clean, dry joint. If it doesn’t work out, we can redo it.
Are you insured?
Yes. Mr Mastic is fully insured.
Is it messy?
We keep the work tidy. We protect what’s around the joints, and the area is left clean when we finish.
