What we need to know

- What’s wrong with the joints now
- How many joints, rooms or windows are involved

- Any previous sealing or DIY work

How we handle new build mastic in Newton Longville
In a new home, every joint should have a clean, even bead. When the finish is smeared, patchy or already cracking, it’s worth putting right early, before water gets into the floor or walls. We work on kitchens, plot handovers and show homes, and people most often call us about plot mastic for developers ahead of handover and internal frame sealant that has split.
Older homes in small places like Newton Longville often have timber floors that move with the seasons, which is why skirting and threshold joints need a flexible sealant, not filler.
All of our work is guaranteed for twelve months, in Newton Longville and everywhere else we cover.

Work for landlords, hotels and businesses
In hotels, rooms out of use cost money, so the work can be planned room by room. We have worked in hotels as well as homes and businesses.
A neglected joint can let water reach the structure, which is a bigger problem in a rented property. Resealing at the right time is simple maintenance that we can handle for you.
Keeping the joints in good condition
Looking after new joints is easy:
- Check bath and shower seals every few months as the house settles
- Do not seal over failed sealant yourself
- Open a window or run the fan after bathing
- Clean sealant with mild detergent, not abrasives
Follow the cure time we give you before the area gets wet. Silicone is usually left for about a day before water reaches them.
Lifting sealant traps moisture and mould behind it. Resealing before mould gets in keeps the job straightforward.
Common problems we fix in Newton Longville
If plaster or screed was still damp when it was sealed, the bond suffers. On a busy site, joints are not always given time to dry first.
Signs it’s time to call us include:
- Skirting joints opening in the first winter
- Kitchen sealant that has pulled off the wall
- Leaking shower tray seals in a new home
- Joints pulling apart as timber shrinks
For new homes near Bletchley station, it’s worth checking the sealant early, while snags are still fresh.

DIY versus a professional finish

Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
