About our new build mastic in Lower Cadsden
A new house keeps drying out and settling for its first couple of years. Timber shrinks, plaster dries and baths and trays bed down, and sealant applied in a hurry at handover can split. We work on plot handovers, bathrooms & en suites and windows & doors, and people most often call us about worktop and upstand sealant coming away and cracks appearing as a new home settles.
Work in a small place like Lower Cadsden just needs the journey and access planning, and once on site, the job is the same as anywhere.
All of our work is guaranteed for twelve months, and the guarantee is the same wherever you are.

Quotes for new build mastic in Lower Cadsden
Your quote is based on your job. We take into account:
- Any mould that needs treating
- How much old sealant there is and how hard it is to remove
- Working hours on commercial sites
- The type of sealant required
What it costs depends on the size of the job, how much old material has to come out and how easy the joints are to reach. You’ll have a clear quote before any work starts, so you know where you stand.
Asking for a quote
When you call or email, these details help:
- The rough size of the job
- What the problem is, such as mould, gaps, leaks or cracking
- Whether it’s a home or a business
- Photos by email, if that is easy
Getting a quote is simple: tell us what needs doing and where. A few pictures by email make the job easier to understand, and we will take it from there.
DIY versus a professional finish
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions, and the work is guaranteed for a year.
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and does not move well, and the joint depth matters as much as the finish.
What happens if it’s left?
Sealant done properly at handover means fewer callbacks. Every return visit for a failed seal takes time. In a small place like Lower Cadsden, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
Homes and businesses are quoted the same way: how much there is to do, how we reach it and what it needs. Ask us for a quote and we will explain what it covers.
