Common problems we fix in Birtley Green
When the heating goes on in the first winter, the house dries fast. Skirting, frames and worktops pull away slightly.
It’s worth asking for a quote if you see:
- Skirting joints opening in the first winter
- Cracks appearing as a new home settles
- Sealant applied over dusty or wet surfaces
- Second-fix sealing on new plots
Around Birtley Green, as everywhere, new build mastic is only as good as the preparation behind it.
What your quote should include
- How the joint is cleaned and prepared
- Is the old sealant removed completely?
- What guarantee comes with the work
- Is VAT in the price?
Why it’s worth doing now in Birtley Green
A tube of sealant from the DIY shop will not fix the cause: dust, no primer and old sealant left in the joint. Proper removal and preparation are what make it last. Around Birtley Green, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
The cost reflects the work involved, not a rough estimate. That’s why we ask about the job first and send you a clear quote before any work starts.
Why book with us
- Trusted Arbo and Everbuild sealants
- White, clear, grey or another colour, product permitting

How the job changes by surface
Skirting and floors
Wet-area floor joints need a flexible seal. We seal them with a sealant suited to wet areas.
Plot handovers
Taking time over preparation reduces return visits. We clean out building dust before sealing and prime where the product needs it.

How much does new build mastic cost in Birtley Green?
Size, access and the old material all affect the cost. Call for a quick quote.
Do you work for landlords and businesses?
Yes, regularly. Several properties can be quoted together, and between tenancies is a good time for the work.
Do you take on second-fix sealing for builders?
Yes. We seal plots to the developer’s programme ready for handover. Tell us the plots and the joints involved for a clear quote.

It depends on whether water is getting through. Failed seals in wet areas need doing now, but cosmetic gaps can wait for movement to slow.

Is it messy?
No. We protect the surfaces around the joints, and we tidy up before we go.

What we do, step by step
A visit follows a simple pattern: we look at the joints together, mask and protect the surrounding surfaces, do the work and tidy away. Most jobs take a few hours for most snagging lists, longer for a run of plots. Somewhere as small as Birtley Green, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- First, the list of joints is agreed from your snagging sheet or plot schedule.
- The failed sealant is removed completely down to clean surfaces.
- Joints are vacuumed and cleaned of building dust.
- We prime where needed and apply a sealant suited to each joint.
- Each bead is tooled and the cure times explained.
How to prepare
- For indoor joints, keep the area dry beforehand if you can
- Tell us about any water getting in
- Move anything stored near the joints
