Can I do it myself?
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is, then guaranteed for a year.
If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it doesn’t work out, we can still put it right.

Keeping the joints in good condition
Simple care keeps the joints in good condition. Our advice:
- Check bath and shower seals every few months as the house settles
- Don’t wait for the house to settle if water is getting through
- Raise failed sealant with the developer while you’re covered
- Wait for the cure time before using a resealed shower
Clean the sealant with a mild detergent and a soft cloth. Avoid abrasive pads and strong solvents as they wear the bead.
Mould takes hold quickly in sealant that has gaps or lifted edges. Dealing with it before it goes black saves a harder job later.
What the job involves on each surface
Kitchens
New-kitchen sealant is often applied in a rush. We take it out and reseal neatly, colour-matched where it shows.
Bathrooms and en suites
En suite showers are a common source of leaks into the room below. A proper reseal keeps water in the tray.
What we do, step by step
We keep the work tidy and contained to the joints we are treating, so you can get on with your day. Expect the work to take anything from a few hours to several days, depending on the number of plots. Somewhere as small as Abbots Worthy, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- First, the list of joints is agreed from your snagging sheet or plot schedule.
- Every bit of the old builder’s sealant is cut out.
- We clean out the dust and grit left from the build.
- 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.
How to prepare
- For indoor joints, keep the area dry beforehand if you can
- Tell us if parking is tricky
- Plan for the work area to be out of bounds to pets and children

Why it’s worth doing now in Abbots Worthy
Resealing everything on a snagging list in one visit is normally simpler than chasing joints one at a time. It’s one visit, one quote and one set of cure times for the lot. Older cottages and farmhouses around Abbots Worthy can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
Every job is a little different, so each one gets its own quote. Size, access and the product the joint needs all make a difference.

What we can’t put right
Some problems need a builder, plumber or other trade rather than us:
- Plumbing faults behind the sealant
- Cracked trays, tiles or worktops
- A tray or bath that is not properly supported, until it’s fixed
Not sure which it is? You can call 0345 464 0079 or send us an email and we’ll tell you honestly before booking.
