About our new build mastic in Marden Beech
Developers send us the plot schedule and we work through it. Bathrooms, en suites, kitchens, frames and skirting are sealed ready for handover. We work on skirting & floors, kitchens and plot handovers, and common reasons people get in touch are cracked caulk along new skirting and shower seals failing in the first year or two.
Around Marden Beech, older homes often have timber floors that move through the year, so skirting and threshold joints need a flexible sealant rather than a rigid filler.
You are covered for a year from the day we finish. If anything isn’t right with it, call 0345 464 0079 or send us an email.

What we do, step by step
There’s no need to move everything out before we come, just the space around the work. We protect the rest, and the work takes a few hours for most snagging lists, longer for a run of plots for a typical job. For a village or hamlet like Marden Beech, the journey is planned in advance: 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.
- We start by going through the snagging items or plot schedule with you.
- Every bit of the old builder’s sealant is cut out.
- Joints are vacuumed and cleaned of building dust.
- 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.
Preparing for the visit
- Mention any sign-in or site rules at work premises
- Let us know if you’ve seen damp or leaks
- For indoor joints, keep the area dry beforehand if you can

How to look after the new joints
So the new joints stay in good condition:
- Keep water off fresh sealant until it has cured
- Look at the sealant regularly in the first couple of years
- Do not wait for the house to settle if water is getting through
- Wipe joints with warm soapy water
Clean the sealant with a mild detergent and a soft cloth. Avoid abrasive pads and strong solvents as they wear the bead.
If a shower tray or bath seal splits in the first year, look for movement. Have it resealed, and the tray or bath checked, before it gets worse.

What affects the cost of new build mastic
Some jobs are bigger than they look, and some smaller. What affects the quote:
- Which sealant suits the joint
- Any mould that needs treating
- How much old sealant there is and how hard it is to remove
- How many areas need sealing
Leaving a failed joint generally makes the job bigger, not smaller. If you are unsure, call 0345 464 0079 or send us an email and we will give you an honest view and a quote.
Helping us quote
You do not need to know the technical terms. It helps if you can tell us:
- Pictures of the joints, sent by email
- If it’s domestic, commercial or a hotel
- Roughly how big the job is
- What the problem is, such as mould, gaps, leaks or cracking
Asking for a quote is easy: tell us what needs doing and where, and roughly how big it is. A few pictures by email make the job easier to understand, and we’ll come back to you with a quote.
What happens if it’s left?
A hairline gap at a skirting can wait, but water getting through cannot. Not sure whether yours can wait? You can ring 0345 464 0079 or send us an email with a few pictures and we’ll tell you. Older cottages and farmhouses around Marden Beech can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
Homes and businesses are quoted the same way: the amount of work, the access and the products needed, plus any working-time requirements on site. Ask us for a quote and we’ll go through it with you.
