Hoe Gate Remedial Sealant
Removing failed, mouldy or leaking sealant and putting it right for homes and businesses in Hoe Gate and across Hampshire. ARBOMaster approved applicators, fully insured, with a 12-month guarantee.
- Thick, messy sealant smeared over tiles
- Movement joints that have split or pulled away
- Kitchen joints letting water behind the worktop
The process
A visit follows a simple pattern: we look at the joints together, mask and protect the surrounding surfaces, carry out the job and clear up. It generally takes a few hours for most joints, depending on how much old sealant has to come out. For a village or hamlet like Hoe Gate, the journey is planned in advance: let us know about lanes, gates and parking. We bring what the job needs, so it can be finished in one trip where possible.
- First we work out whether the problem is the sealant, movement or a leak.
- Each layer is cut out and the residue cleaned off.
- Mould is treated and the joint dried.
- 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.
How to prepare
- On commercial sites, let us know about site rules
- For indoor joints, keep the area dry beforehand if you can
- Let us know about stairs, lifts or work at height

Remedial sealant for homes and businesses in Hoe Gate
Movement and expansion joints fail when the sealant cannot stretch. The old sealant comes out and backing goes in to control the depth, before resealing with a flexible product suited to the movement. We work on botched or over-sealed joints, failed movement joints and expansion joints, and people most often call us about dark patches showing through the sealant and kitchen joints letting water behind the worktop.
Homes around Hoe Gate are mostly houses and cottages rather than flats. Sealant and grout wear out here just as they do anywhere: everything old comes out before the new sealant or grout goes in.
Every job comes with our one-year guarantee, wherever you are in Hampshire.

What else we do in Hoe Gate
Looking after it afterwards
To keep the joints looking good and working properly:
- Ask why a joint failed before redoing it
- Do not add new sealant on top of old
- Keep an eye on the ceiling below the bathroom
- Check trays and worktops don’t move
Leave the new joint to cure fully before it gets wet or moves: follow the cure time we give you.
A split movement joint lets rain into walls and floors, and the longer it’s left, the more the joint edges break down. Resealing while the edges are sound is simpler.
Signs you need remedial sealant in Hoe Gate
A lot of failed joints have been sealed over rather than replaced. Silicone does not bond to silicone, so the top layer lifts and water and mould collect between the two.
The most common problems we see are:
- Caulk or the wrong sealant used in a wet area
- Floor or wall movement joints that have failed
- Dark patches showing through the sealant
- Gaps opening along the back of the worktop
If you let a flat or house near Portchester station, a joint that keeps failing is best fixed properly while the property is empty.

What remedial sealant looks like in Hoe Gate
Hard water is the norm across most of the South East, which leaves limescale on sealant, grout and fittings.
Managing a site like Newtown Soberton Infant School? Then its toilets, changing areas and kitchens need their sealant renewed like any other building’s. If you live in an older home near Church of the Holy Trinity, older homes can move a little, which is hard on rigid grout and tired sealant.

Why it’s worth doing now in Hoe Gate
Leaks that are left keep doing damage out of sight: soaked floorboards, ceiling stains below and blown plaster. Dealing with the joint now is a small job by comparison. Where a wall is exposed, as many are in small places like Hoe Gate, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
A few things move the cost up or down: the old material and how easily it comes out, any mould to treat, and whether we need extra access for height. We take all of that into account in your quote.

What the job involves on each surface
Movement & expansion joints
Bonding on three sides is a common reason movement joints tear. Backing rod or bond-breaker tape prevents it, so the sealant grips the two sides only.
Windows & doors
A frame that keeps leaking may not be the mastic. We check the joint and tell you if it looks to be something else.
What we can’t put right
New sealant cannot fix everything, and we’d rather say so up front. Sealant will not put right:
- A bath, tray or worktop that moves until it’s properly fixed
- A leaking trap, valve or supply pipe
- Older mastics that may need an asbestos check before removal
If in doubt, phone 0345 464 0079 or email us and we will say what we think before you book.
Joints and surfaces we work on
- Failed movement joints
- Botched or over-sealed joints
- Leaking tray & enclosure joints
