Remedial sealant for homes and businesses in Hartwell
Some sealant jobs are not a simple reseal, because someone has already had a go. Silicone laid over silicone, smears across tiles, the wrong product in a moving joint or mould trapped underneath all have to come out before the joint can be done properly. Common call-outs are for sealant applied over old sealant that has lifted and sealant peeling off a dusty or damp surface, across mouldy bath & shower sealant, expansion joints and shrunken worktop sealant.
Being in a small place like Hartwell makes no difference to the job itself: the journey and access are simply agreed in advance. Once we are there, the bathroom or kitchen gets the same care as anywhere else.
Big or small, it’s backed by our 12-month guarantee.

Leave it or put it right?
Spraying mould remover on a sealed-over joint doesn’t reach what’s underneath. Removal is the only way to get at it, so the joint can be treated and resealed. Older cottages and farmhouses around Hartwell can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
No two jobs are quite the same, so we quote each one individually. Size, access and the product the joint needs all play a part, and we will explain the quote if you ask.

How to look after the new joints
Once the sealant has cured, a few habits help it last:
- Always have old sealant cut out, not covered
- Find out why the sealant failed first
- Don’t wait for a small gap to become a leak
- Report a tray that rocks or a worktop that lifts
Where we have pointed out another fault, have it put right, or the new joint may fail again.
Movement joints that have split let water into the structure, and left long enough, the edges of the joint can crumble. A joint with sound edges is far easier to reseal.
What the job involves on each surface
Mouldy bath & shower sealant
Mould often spreads under the bead as well as through it. We treat the exposed joint once the bead is out.
Movement & expansion joints
Some movement joints have been filled with mortar or grout. We rake that out where it can be removed and seal with a flexible product.
The process
Good joint work is mostly preparation, so that’s where we spend the time. Joints are cleaned back and dried before anything new goes in. All told, the work takes a few hours for a typical bath or shower, longer where several layers have been applied. In a small place like Hartwell, access is generally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- Surrounding tiles, trays and frames are protected first.
- Every layer of failed sealant is stripped out.
- The joint is degreased and checked for movement and leaks.
- Once dry, a suitable sealant is applied and tooled.
- We give you the cure time and explain what caused the failure.
Preparing for the visit
- Let us know about earlier repairs to the joints
- For business premises, tell us about site rules or sign-in
- For indoor joints, keep the area dry beforehand if you can

Remedial sealant around Hartwell
Most of the South East has hard water, which leaves limescale on sealant, grout and fittings.
For an older house near a landmark such as St Mary's Church, timber floors under older bathrooms flex, so joints need a sealant that moves with them. Rented homes near Aylesbury station change hands often, and failed or mouldy sealant is worth putting right between tenancies, before it turns into a leak. If you look after a building such as Stone Church of England Combined School, we reseal washrooms and kitchens in schools and businesses as well as homes.

What sealant work cannot fix

- Sealant in an older building that needs testing for asbestos first

- A tray or bath that is cracked

DIY sealant or a professional job?
If you do try it yourself, take your time over the 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.
The difference is mostly in the preparation and the 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.
