New build mastic in Dagnall, done properly
Across Dagnall, we work for both new-home owners and the builders handing those homes over. One shower or a whole phase of plots, the method doesn’t change: remove, clean, prime where needed, then a neat new bead. If you have plot mastic for developers ahead of handover and cracked caulk along new skirting, we can put it right, on kitchens, show homes and skirting & floors alike.
Somewhere as small as Dagnall, new homes tend to be conversions, self-builds or a few houses rather than an estate. Every one needs its sealant and floor joints done properly, whatever the size of the site.
Your job is guaranteed for a year, as with all our work.

Why deal with it now?
A quick bead over the top of the old sealant can look fine at first, but it can’t bond to what’s underneath. A lasting seal starts with removing the old one completely. In a small place like Dagnall, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
Commercial jobs are quoted on the same basis as homes: the amount of work, the access and the products needed, plus any working-time requirements on site. Ask us for a quote and we will explain what it covers.

How the visit works
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. For a village or hamlet like Dagnall, the journey is planned in advance: tell us about narrow lanes, gates, long drives and where we can park. Everything for the job comes with us, so a second trip is avoided where possible.
- We go through the snagging list or plot schedule and agree the joints to do.
- The old bead comes out in full, with no layer left behind.
- We clean off dust from the build and prime the surfaces where the product needs it.
- New sealant suited to each joint is applied and tooled neatly.
- Each area is checked and left with its cure time.
Getting ready for the visit
- Mention any leaks or damp you’ve noticed
- Let us know about parking restrictions
- Try not to wet indoor joints just before the visit

Common problems we fix in Dagnall
Later trades and the final clean can damage fresh sealant. A bead disturbed before it has cured may never seal properly and it shows once the home is in use.
People normally contact us when they notice one of these:
- Shower seals failing in the first year or two
- Joints pulling apart as timber shrinks
- Untidy sealant flagged on a snagging list
- Gaps between new skirting and floors
In and around Dagnall, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.
Questions to ask before you book
- What the cure time is
- Whether VAT is included
- The length of the guarantee
- How the joint is cleaned and prepared
For landlords and businesses
Whether it’s one flat or a portfolio, you get the same standard of work: old sealant fully removed, joints prepared properly and a 12-month guarantee.
Letting agents and landlords in Dagnall can book us as well as householders. Resealing between tenancies is a simple way to keep a property in good order.
When it isn’t the sealant
A few problems are outside what sealant work can do:
- Settlement cracks that need a surveyor
- Leaking fittings rather than failed sealant
- Deciding who is responsible under a builder’s warranty
Not sure which it is? You can phone 0345 464 0079 or email us and we will tell you honestly.

Do you take on second-fix sealing for builders?

Which products do you use?
Products from Arbo and Everbuild, among others, chosen to suit the joint. We will tell you what we’re using and why.
Can you quote for more than one area?
Yes. More than one area can go on one quote.
Is it messy?
No. We work neatly, protect the area around the joints and tidy up afterwards.
What colour sealant will you use?
It depends on the joint: white or clear for most sanitary joints, colours for worktops, floors and frames. We will agree it with you first.
Do you hold any approvals?
Yes. ARBOMaster is the approved applicator scheme for Arbo sealants, and we’re part of it.
How to look after the new joints
No joint lasts for ever, but care makes a real difference. Our tips:
- Do not seal over failed sealant yourself
- Clean sealant with mild detergent, not abrasives
- Report sealant problems to your builder during the snagging period
- Look at the sealant regularly in the first couple of years
Follow the cure time we give you before the area gets wet. Silicone is usually left for about a day.
Early snagging is easier snagging. Left alone, a small crack can become a leak.
