Surface by surface

About our remedial sealant in Hitchin
The wrong product in the wrong joint won’t last, however tidy it looks. We take it out and use a sealant made for that joint. We work on leaking tray & enclosure joints, botched or over-sealed joints and expansion joints, and people most often call us about repeat leaks from the same joint and decorators’ caulk around a bath or shower.
Homes around Hitchin have been extended and refitted over the decades. Sealant run over the top of an old bead is a common cause of leaks and mould, so we take every joint back to clean before anything new goes in.
We guarantee the work for a year. If there’s a problem with our work within the year, let us know and we’ll sort it.

What remedial sealant looks like in Hitchin
Hitchin has hotels and guest accommodation nearby. As well as homes, we work in hotel bathrooms, where resealing and regrouting can be done room by room. Hard water is the norm across most of the South East, which leaves limescale on sealant, grout and fittings, and it has to be cleaned off before new sealant goes in.
If you live in an older home near Church of the Holy Saviour, walls and floors in older homes can move, and sealant and grout show it first. If you let a flat or house near Hitchin station, a joint that keeps failing is best fixed properly while the property is empty.

Can I do it myself?
If you’re set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it does not work out, we can still put it right.
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is.
Why it’s worth doing now in Hitchin
Hidden water does the most damage: soaked floorboards, ceiling stains below and blown plaster. By comparison, sorting the joint is quick. Gaps in sealant and mould in the bead never get better on their own, and in a busy home in Hitchin they get worse with every use. Now is the easy time to put it right.
What you pay reflects the work, not a rough estimate. That’s why we ask about the job first.

Keeping the joints in good condition
Simple care keeps the joints in good condition. Our advice:
- Never seal over old silicone
- Report a tray that rocks or a worktop that lifts
- Keep an eye on the ceiling below the bathroom
- Get the cause of a repeat leak found before resealing
Clean gently: a mild cleaner and a soft cloth, with no blades or scourers.
Mould under a second layer of sealant keeps growing out of sight. When it finally shows, the whole bead needs to come out.
When to call us in Hitchin
Using the wrong product is a common cause: caulk where it gets wet, rigid sealant where things move, or an acetoxy silicone on a surface it can mark. None of them last.
Look out for these signs:
- Sealant peeling off a dusty or damp surface
- Repeat leaks from the same joint
- Black mould underneath the bead
- Thick, messy sealant smeared over tiles
For site and facilities teams at buildings such as Hitchin Girls' School, we reseal washrooms and kitchens in schools and businesses as well as homes.
