Common questions in Hounslow
Is parking a problem for a job in Hounslow?
In much of London, parking needs planning: a visitor permit or a bay close to the door helps a lot, so mention what’s available when you book.
I let a flat near Sunbury station. Can you help?
Yes. We work for letting agents and landlords as well as homeowners, and several properties can be quoted together. Just ring 0345 464 0079 or send us an email with the address and what needs doing, and we will send you a clear quote.
Is it messy?
No. The area is protected while we work and cleaned up afterwards.
How long should I leave it?
It depends on the product and the conditions. Before we leave, we will tell you the cure time.
Are you fully insured?
Yes. We are fully insured for every job we do.
Does someone need to be in?
That depends on where the joints are. For work indoors, someone needs to let us in.
Which products do you use?
It depends on the joint: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. Brands we use include Arbo and Everbuild.
Is there any odour?
That depends on the sealant. Some smell for a while, some hardly at all, and any smell fades as they cure.
Remedial sealant in Hounslow
With more than 20 years’ experience, our applicators have seen most of the ways sealant can fail. We are ARBOMaster approved and fully insured, and remedial work carries our 12-month guarantee. If you have over-sealed joints coming away and decorators’ caulk around a bath or shower, we can help.
Hard London water leaves limescale on sealant, grout and taps alike. In Hounslow, remedial sealant is as much about a room looking cared for as about keeping water out.
All of our work is guaranteed for twelve months.

How it works
There is not much for you to do on the day. Show us the job and we will take it from there. The job generally takes a few hours for most joints, depending on how much old sealant has to come out. In Hounslow, as in most of London, parking needs a little planning. It helps if you can point us to a visitor permit or a bay close to the door.
- We look at how the sealant has failed and check for movement or a leak path.
- We strip the joint completely, removing any layers below.
- We clean the joint, treat any mould and let it dry.
- Moving joints get backing and a flexible sealant to suit.
- Finally we finish the joint and talk you through what we found.
Before we arrive
- Let us know if you’ve seen damp or leaks
- Mention if the joints have been sealed before
- Let us know about parking restrictions

What happens if it’s left?
Repeat failures have a cause. Finding it, whether movement, water from elsewhere or an unsuitable product, ends the cycle. Damp from a failed joint spreads quietly in older London brickwork and timber, and once it shows in Hounslow, the repair is bigger than a sealant job.
Homes and businesses are quoted the same way: how much there is to do, how we reach it and what it needs. Call for a quick quote and we will explain what it covers.

What remedial sealant looks like in Hounslow
London has a lot of flats and conversions, and a failed shower or bath seal in one can show up on the ceiling below, so tired sealant is best dealt with early. London has hard water, so limescale builds up on sealant, grout and fittings.
In the older streets around Church of St Dunstan, older homes can move a little, which is hard on rigid grout and tired sealant. If you let a flat or house near Sunbury station, a joint that keeps failing is best fixed properly while the property is empty.

How the job changes by surface
Movement & expansion joints
Joints filled with mortar, grout or rigid filler can’t move. We rake that out where it can be removed and seal with a flexible product.
Mouldy bath & shower sealant
Mould can sit behind the silicone, not just in it. We treat the exposed joint once the bead is out so the new sealant starts clean.
How to look after the new joints
Looking after new joints is easy:
- Never fill a movement joint with mortar or grout
- Air the bathroom so the sealant can dry
- Get the cause of a repeat leak found before resealing
- Deal with small splits early
Where we have pointed out another fault, have it put right, because the new sealant cannot hold back a problem underneath.
A failing joint rarely gets better on its own. Each use pushes more water behind the bead, into whatever is behind or below. Early action keeps it to a sealant job.
When it isn’t the sealant
We will always be straight with you, so here’s what sealant can’t fix:
- Plumbing leaks behind walls or under trays
- Water damage behind tiles that needs a tiler
- Sealant in an older building that needs testing for asbestos first
If in doubt, phone 0345 464 0079 or drop us an email and we will say what we think.
Surfaces we seal
- Shrunken worktop sealant
- Mouldy bath & shower sealant
- Expansion joints
- Failed movement joints
- Botched or over-sealed joints
- Leaking tray & enclosure joints
Do you need remedial sealant in Hounslow?
Silicone only bonds to surfaces that are clean and dry. Soap film, dust, damp or old residue stop it gripping, so it starts lifting sooner than it should.
Keep an eye out for any of the following:
- Mould trapped under a layer of silicone
- Over-sealed joints coming away
- Decorators’ caulk around a bath or shower
- Sealant that came away because the surface wasn’t prepared
As a London address, Hounslow can be tricky for parking: let us know about parking bays, permits or a driveway.
