Remedial sealant & repairs in Upham, Hampshire

- Products that weren’t meant for the joint
- Sealant applied over old sealant that has lifted
Can I do it myself?
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
How we handle remedial sealant in Upham
A movement joint stops working when its sealant splits or sets hard. The old sealant comes out and backing goes in to control the depth, before resealing with a flexible product suited to the movement. If you have sealant applied over old sealant that has lifted and gaps opening along the back of the worktop, we can put it right, on expansion joints, botched or over-sealed joints and leaking tray & enclosure joints alike.
Homes around Upham are mostly houses and cottages rather than flats, some with bathrooms tucked into older rooms or extensions. The work is the same as anywhere: everything old comes out before the new sealant or grout goes in.
Whatever the size of the job, it’s backed by our 12-month guarantee.

What happens on the day
At the end, we look at the finished work together and explain the cure time. The visit itself usually takes a few hours for most joints, depending on how much old sealant has to come out, depending on the amount of work. In a small place like Upham, access is generally the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- The failure is looked at first, so we know whether it’s sealant, movement or water from elsewhere.
- Each layer is cut out and the residue cleaned off.
- We treat any mould and dry the joint thoroughly.
- We reseal with a product suited to the joint, backed where needed.
- The joint is tooled and you are told about anything else we found.
Getting ready for the visit
- Tell us about any water getting in
- For business premises, tell us about site rules or sign-in
- Keep pets and children clear of the area while we work

What remedial sealant looks like in Upham
Hard water is the norm across most of the South East, so limescale builds up on sealant, grout and fittings.
Managing a site like Upham Church of England Aided Primary School? Then we reseal washrooms and kitchens in schools and businesses as well as homes. If you live in an older home near Church of St Mary, older homes can move a little, which is hard on rigid grout and tired sealant. Letting a property close to Hedge End station? Then a joint that keeps failing is best fixed properly while the property is empty.

Keeping the joints in good condition
A little care helps the new joints last. We recommend:
- Do not add new sealant on top of old
- Have loose fittings fixed before resealing
- Never fill a movement joint with mortar or grout
- Keep an eye on the ceiling below the bathroom
Clean gently: a mild cleaner and a soft cloth, with no blades or scourers.
A failing joint rarely gets better on its own. Every shower or downpour sends more water through, into whatever is behind or below. Sorting it early limits the damage.
What happens if it’s left?
Hidden water does the most damage: wet floors, stained ceilings and swollen worktops. By comparison, sorting the joint is quick. Around Upham, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
