How we handle new build mastic in Upper Halliford
Failed shower seals, gaps along the skirting and messy beads are common items on a new-home snagging list. If you are still within the builder’s snagging or warranty period, tell them first, and if it is not put right, get in touch with us. We work on skirting & floors, bathrooms & en suites and windows & doors, and the jobs we see most are skirting joints opening in the first winter and internal frame sealant that has split.
Older homes in small places like Upper Halliford often have timber floors that move with the seasons, so skirting and threshold joints need a flexible sealant rather than a rigid filler.
You get a 12-month guarantee, the same in Upper Halliford as everywhere else we work.

What sealant work cannot fix
New sealant cannot fix everything, and we will tell you before work begins. Sealant will not put right:
- Broken tiles or a split tray
- Deciding who is responsible under a builder’s warranty
- Cracking that points to a structural problem
If you are not sure, just ring 0345 464 0079 or drop us an email and we’ll give you a straight answer.

What affects the quote in Upper Halliford
There’s no set price list, because jobs vary so much. What we look at:
- The number of rooms or windows
- The product the joint needs
- How much there is to do
- Mould in or behind the old joints
Leaving a failed joint generally makes the job bigger, not smaller, as water and mould keep getting in. If you’re unsure, call 0345 464 0079 or drop us an email and we’ll give you an honest view and a quote.
Helping us quote
Before you ask for a quote, have a think about:
- How many joints, rooms or windows are involved
- Where the property is
- A few photos by email, if you can
- Whether it has been sealed before
Call for a quick quote, or send an email if you’d rather. Describe what needs sealing and we will talk you through the work.
How to look after the new joints
How long the joints last depends on use and care. Here’s what we suggest:
- Get a leaking seal dealt with right away
- Avoid scourers and strong chemicals on sealant
- Keep photos and emails about snagging items
- Keep water off fresh sealant until it has cured
Wipe the sealant with warm soapy water. Keep scourers and harsh chemicals off it as they wear the bead.
Early snagging is easier snagging. Small faults turn into leaks if left.
What happens if it’s left?
Water getting past a failed seal in a new build reaches walls and floors that are still settling. Dealing with it early keeps the damage away from ceilings, floors and finishes. In a small place like Upper Halliford, homes can be exposed to wind and rain, which finds any gap, 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: the amount of work, the old material and the access. You’ll know the price before we begin.

Upper Halliford questions
Is Upper Halliford within the area you cover?
Yes, Upper Halliford is covered. We work across London and the South East, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
Is Upper Halliford in your area for new build mastic?
Yes, Upper Halliford is within the area we cover. Our work covers London and the South East. Just phone 0345 464 0079 or send us an email with a few details of the job.
Who should fix failed sealant in a new build?
While the snagging or warranty period runs, the builder should be your first contact. If it is not sorted, or keeps failing, get in touch with us.
Do you take on second-fix sealing for builders?
Yes. We take on second-fix sealant work across new plots. We clean and prime joints properly to keep callbacks down.
Can you work on commercial sites?
Yes, regularly. We can plan bigger jobs in stages to suit the site.
Is the work guaranteed?
Yes, for a year. If there’s a problem with our work in that time, tell us and we’ll put it right.
Will you just run a new bead over the existing one?
No. Fresh silicone doesn’t stick to the old layer, so it soon lifts and traps water. The old sealant always comes out first.
What does new build mastic cost?
It depends on the job, so we quote each one individually. To get one, phone 0345 464 0079 or email us and let us know what needs doing and where.

What we are called out for in Upper Halliford
Sealant is often one of the last jobs before handover. Joints are not always cleaned of dust or primed, so the bead never bonds properly.
The problems people normally mention when they call include:
- Beads laid onto grit and dust from the build
- Worktop and upstand sealant coming away
- New-build shower sealant that has already split
- Gaps between new skirting and floors
For new homes near Upper Halliford station, it’s worth checking the sealant early, while snags are still fresh.
