When to call us in Blindley Heath
Not every new-build joint gets the right sealant: decorators’ caulk in a wet area, or a stiff sealant where there’s movement. Both fail early.
The most common problems we see are:
- Joints pulling apart as timber shrinks
- Skirting joints opening in the first winter
- Worktop and upstand sealant coming away
- Sealant applied over dusty or wet surfaces
In and around Blindley Heath, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.

Blindley Heath: your questions answered
Can you do new build mastic in Blindley Heath?
Yes. Our work covers London and the South East, and Blindley Heath is part of that. Just phone 0345 464 0079 or email us with a few details of the job.
Do you cover smaller places like Blindley Heath?
Yes. Blindley Heath is within the area we cover, which takes in towns, villages and rural addresses. We work across London and the South East. Just mention lanes, gates or anything else about the route when you book.
Is there a guarantee?
Yes, for a year. If anything is not right with the work within the year, let us know and we will sort it.
How much does new build mastic cost in Blindley Heath?
The cost depends on the size of the job, access and how much old sealant has to come out. Ask us for a quote and we’ll talk you through it.
Should I go to my builder first?
If you’re still within the builder’s snagging or warranty period, report it to them first. If it is not sorted, or keeps failing, get in touch with us.
Does someone need to be in?
We need access to the joints, so we will agree that with you when we book. For inside work, that normally means someone being in.
Where is Mr Mastic based?

Keeping the joints in good condition
To keep the joints looking good and working properly:
- Record problems with dated photos
- Ventilate bathrooms well, especially in the first year
- Resist patching a failed seal with a tube from the DIY shop
- Clean sealant with mild detergent, not abrasives
Follow the cure time we give you before the area gets wet. Silicone is generally left for about a day.
Early snagging is easier snagging. Small faults turn into leaks if left.
For landlords and businesses
We work for landlords and letting agents as well as homeowners. Resealing between tenancies keeps a property looking cared for before the next move-in.
Housing providers, facilities teams and property managers book us too in Blindley Heath and across Surrey. We can quote a run of properties together, and we are fully insured.
How the job changes by surface
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.
Skirting and floors
Where the floor meets a bath panel or kitchen plinth, the joint keeps mop water out. We seal them with a sealant suited to wet areas.
The process
At the end, we look at the finished work together. The visit itself generally takes a few hours in a single home, depending on the size of the job. For a village or hamlet like Blindley Heath, the journey is planned in advance: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.
- Each joint is checked for movement before any work starts.
- Old sealant is cut out and the joints cleaned.
- Joints are dried and primed where the product calls for it.
- New sealant goes in, with baths filled first so they’re at their heaviest.
- The finished joints are checked and the cure times given.
Getting ready for the visit
- Tell us about access, such as stairs, a lift or high-level joints
- For indoor joints, keep the area dry beforehand if you can
- Plan for the work area to be out of bounds to pets and children

Why it’s worth doing now in Blindley Heath
A quick bead over the top of the old sealant can look fine at first, but it won’t bond to the old layer. Taking it all out and starting again is the only way to get a lasting seal. Where a wall is exposed, as many are in small places like Blindley Heath, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
Homes and businesses are quoted the same way: the amount of work, how we reach it and what it needs, along with when we can work on site. Ask us for a quote and we’ll go through it with you.
What you get with us
- A sealant colour to suit the surroundings
- Domestic, commercial and hotel work
- White, clear, grey or coloured to suit, where the product allows
- Quality sealants from Arbo and Everbuild
