When to call us in Hemsted
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.
If you can see any of these, it’s time to have the joints looked at:
- Untidy sealant flagged on a snagging list
- Beads laid onto grit and dust from the build
- Leaking shower tray seals in a new home
- Sealant work across a run of new homes
In and around Hemsted, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.

New build mastic for homes and businesses in Hemsted
A new build should have a neat, sound bead at every joint. Smeared, patchy or cracked sealant is worth sorting early, before water gets into the floor or walls. If you are dealing with cracked caulk along new skirting and shower seals failing in the first year or two, we can put it right.
Around Hemsted, older homes often have timber floors that move through the year, so skirting and threshold joints need a flexible sealant rather than a rigid filler.
A 12-month guarantee comes as standard, so you are covered after we have gone.

Will there be a smell?
Some sealants have a smell while they cure, but it fades. Ventilation helps.
Will the old sealant be removed?
Yes. All of the old material is cut out and the joint cleaned before applying anything new.
Can you quote for more than one area?
Of course. Combining jobs makes good use of the visit.
What happens if it’s left?
Running a new bead over the builder’s sealant might look tidy for a few weeks, but it won’t bond to the old layer. Taking it all out and starting again is the only way to get a lasting seal. Where a wall is exposed, as many are in small places like Hemsted, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
What you pay reflects the work, not guesswork. That is why we ask about the job first.

DIY versus a professional finish
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions, then guaranteed for a year.
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 fails, we can still redo it.
What sealant work can’t fix
We won’t take on work that won’t last, so here’s what sealant cannot put right:
- Cracked trays, tiles or worktops
- Settlement cracks that need a surveyor
- Disputes or warranty claims with your builder
If you are not sure, just phone 0345 464 0079 or email us and we’ll give you a straight answer.

Looking after it afterwards
Aftercare is simple:
- Act quickly if a seal starts to leak
- Check bath and shower seals every few months as the house settles
- Raise failed sealant with the developer while you’re covered
- Photograph failed sealant before it’s redone
Avoid standing on the rim of the bath or the edge of the tray while the sealant cures. Report any movement in a bath or tray.
Lifting sealant traps moisture and mould behind it. Resealing before mould gets in saves a harder job later.
