Do you need new build mastic in Lunsford's Cross?
If plaster or screed was still damp when it was sealed, the bond suffers. On a busy site, joints aren’t always given time to dry first.
These are the problems we’re asked about most:
- Messy sealant that spoils new finishes
- Gaps behind new kitchen upstands
- Internal frame sealant that has split
- Skirting joints opening in the first winter
In and around Lunsford's Cross, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.
Questions to ask before you book
- How long the guarantee is
- Whether all the old sealant comes out first
- Whether the sealant suits the joint
- Whether they’re fully insured
New build mastic for homes and businesses in Lunsford's Cross
We carry out plot mastic and second-fix sealing for builders, and snagging reseals for new-home owners. Both get the same care over preparation. We work on windows & doors, show homes and plot handovers, and common reasons people get in touch are gaps between new skirting and floors and cracked sealant around new window and door frames.
For a small place like Lunsford's Cross, the journey and access are planned in advance, and once on site, the job is the same as anywhere.
Our work is backed for twelve months, in Lunsford's Cross and everywhere else we cover.

What happens if it’s left?
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 Lunsford's Cross, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
Rather than a set price list, we price the job in front of us: how many joints, what’s in them now and how we reach them. The price is agreed before we begin.
What you get with us
- Arbo and Everbuild products
- Colour agreed with you before any work starts
- A choice of colours where the product allows
- Homes, businesses and hotels

Should I try it myself first?
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is.
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
What we do, step by step
Once we’re on site, we compare the joints with what we discussed. If anything is different, we explain it before carrying on. Most jobs then take anything from a few hours to several days, depending on the number of plots. Somewhere like Lunsford's Cross needs a little journey planning: let us know about lanes, gates and parking. We bring what the job needs, so it can be finished in one trip where possible.
- Each joint is checked for movement before work begins.
- We remove the failed sealant and clean the joints.
- We make sure the joints are dry and prime them if needed.
- Baths are filled with water, then the new sealant is applied.
- The finished joints are checked and the cure times given.
How to prepare
- Keep pets and children clear of the area while we work
- For indoor joints, keep the area dry beforehand if you can
- Mention any parking rules near the property
