New build mastic in Nash Lee

If you are still within the builder’s snagging or warranty period, tell them first, and if it isn’t put right, get in touch with us. We work on show homes, bathrooms & en suites and skirting & floors, and common reasons people get in touch are second-fix sealing on new plots and cracked sealant around new window and door frames.

How the job changes by surface
Windows and doors
Draughts around new frames are often a sealant gap. We check and reseal the frame edges.
Kitchens
Worktops in new homes can move slightly as the house dries, which opens gaps along the back. We reseal them with a flexible sealant.
Signs you need new build mastic in Nash Lee
The first winter with the heating on dries a new home quickly. Gaps open along skirting, frames and worktops.
Most people get in touch after spotting something like this:
- Worktop and upstand sealant coming away
- Internal frame sealant that has split
- New-build shower sealant that has already split
- Sealant work across a run of new homes
If you’ve bought a new home near Stoke Mandeville station, the sealant around baths, showers and frames is worth checking in the first year or two.

Keeping the joints in good condition
Once the sealant has cured, a few habits help it last:
- Report sealant problems to your builder during the snagging period
- Wipe joints with warm soapy water
- Ventilate bathrooms well, especially in the first year
- Avoid running a DIY bead over the old one
Clean the sealant with a mild detergent and a soft cloth. Keep scourers and harsh chemicals off it, which can damage the surface.
A failed seal in a new home lets water into joists, plasterboard and ceilings. Catching it early keeps the fix to the sealant and the new finishes intact.
DIY versus a professional finish
If you’re set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it does not work out, we can still put it right.
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.
What affects the quote in Nash Lee
Every job gets its own quote. These are the things that affect it:
- How many areas need sealing
- Whether there’s mould to deal with
- Any working-time requirements on site
- How much old sealant there is and how hard it is to remove
Instead of a standard rate, we price the job in front of us: how many joints, what’s in them now and how we reach them. You will know the price before we begin.
Helping us quote
To make quoting easier, please include:
- If it’s domestic, commercial or a hotel
- Where the job is, and your postcode
- If someone has resealed it before
- The problem you’ve noticed
Asking for a quote is easy: tell us what needs doing and where and its rough size. A few pictures by email make the job easier to understand.

How it works
Before we leave, we go over the finished joints with you and explain the cure time. The visit itself normally takes a few hours for most snagging lists, longer for a run of plots, depending on the size of the job. In a small place like Nash Lee, access is usually the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- 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.
- Primer goes on where the surface and product need it, then the new sealant.
- We tool every joint neatly and tell you when each area can be used.
Before we arrive
- Clear the area around the work
- Let us know about stairs, lifts or work at height
- Let us know if you’ve seen damp or leaks
