Why it’s worth doing now in Harefield
Remedial work takes longer than a straight reseal, but not by much: it takes a few hours for most joints, depending on how much old sealant has to come out. Compared with chasing the same leak every few months, it’s time well spent. In a smaller place like Harefield, wherever a wall is exposed, a failed outside joint is a real source of damp. Indoors, a failed seal lets water into floors and panels as it would anywhere.
There are no prices on our website, because the cost depends so much on the job itself. For a quick quote, please call 0345 464 0079 or send us an email.

About our remedial sealant in Harefield
A joint that keeps failing normally has a reason. Movement, the wrong product or a leak from somewhere else will defeat even a perfect bead. We look for the cause before we reseal. Typical jobs include kitchen joints letting water behind the worktop and sealant peeling off a dusty or damp surface, on botched or over-sealed joints, expansion joints and failed movement joints.
Even in a smaller place like Harefield, bathrooms and kitchens see heavy daily use. Whether it’s a cottage bathroom or a newer en suite, the approach is the same: old sealant or grout cut out, joints cleaned and dried, and a fresh finish laid.
Your job is guaranteed for a year, as with all our work.

How the job changes by surface
Over-sealed & botched joints
A thick bead smeared across tiles often hides mould or gaps. Taking it back shows what’s underneath, then reseal neatly.
Worktops & kitchens
Shrunken worktop sealant leaves a gap that lets water into the back edge. We strip it, degrease the joint and reseal in a colour to suit.

Harefield homes and their sealant
Harefield is close to the coast. Near the coast, holiday lets and guest houses can see bathrooms used by one guest after another, and sealant and grout that work that hard wear out sooner. 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.
For site and facilities teams at buildings such as Harefield Primary School, we reseal washrooms and kitchens in schools and businesses as well as homes. For landlords with property near Bitterne station, failed or mouldy sealant is worth putting right between tenancies, before it turns into a leak.
Harefield is about 2 miles east of Southampton, in Southampton. Harefield gets the same service as everywhere we cover: old sealant removed completely, careful preparation and a 12-month guarantee. Our Southampton coverage runs to 40 places, Harefield among them.

What we are called out for in Harefield
How a joint is built matters as much as the product. A bead bonded on three sides, or laid too thick, cannot flex, and tears at the first real movement. Backing sets the depth and stops that.
Look out for these signs:
- Movement joints that have split or pulled away
- Smears and lumps from a botched reseal
- Decorators’ caulk around a bath or shower
- A second bead peeling off the first
Homes close to Church of St James include some older properties, and timber floors under older bathrooms flex, so joints need a sealant that moves with them.
What your quote should include
- Whether all the old sealant comes out first
- What insurance they hold
- What guarantee comes with the work
- What happens if the job turns out different
Should I try it myself first?
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
Landlord and commercial work in Harefield
Whether it’s one flat or a portfolio, you get the same standard of work: the old material taken out, careful preparation and a 12-month guarantee.
Mouldy or split sealant often shows up at the end of a tenancy, and it’s quick to put right between tenancies. Several properties can be quoted together.
How the visit works
A visit follows a simple pattern: we look at the joints together, protect the area around them, do the work and clear up. Most jobs take a few hours for most joints, depending on how much old sealant has to come out. Parking around Harefield is usually easier than in a town centre, but mention any lanes, gates or long drives. For outside work, side access and the height of the joints help us plan.
- We protect the surfaces around the joint.
- The botched or failed sealant is cut away completely.
- We clean and degrease the joint and look for signs of movement or water.
- New sealant goes in once the joint is dry, and is tooled smooth.
- You get the cure time and our view on why the joint failed.
Preparing for the visit
- On commercial sites, let us know about site rules
- Tell us about access, such as stairs, a lift or high-level joints
- Keep children and pets away from the work area

Harefield questions
I let a flat near Bitterne station. Can you help?
Yes, rental work is part of what we do. Just ring 0345 464 0079 or email us and tell us about the property, and we will give you a clear quote.
Do you cover Harefield for remedial sealant?
Yes, Harefield is within the area we cover. Our work covers London and the South East. Just ring 0345 464 0079 or send us an email with a few details of the job.
Do you remove the old sealant?
Yes, every time. New sealant will not bond properly to old, so any old material comes out before anything new goes in.
Do I have to be there?
That depends on where the joints are. Inside work needs someone to give us access.
Can you work on commercial sites?
Yes. Commercial and hotel work is a large part of what we do, as well as homes. Working times can be discussed when we quote.
Can I add another job to the visit?
Yes. Just list everything you need and you will get one quote.
Can old silicone be taken off without scratching the tiles?
Yes. The old bead is cut and lifted with tools that suit the surface, then clean off the residue. We point out any damage that’s already there.
What if the leak isn’t the sealant?
We check for that before we reseal. If we find the leak is elsewhere, we tell you before going further.
