Common questions in Chadwell St Mary
Can you help a landlord with a rental near East Tilbury station?
Yes, we work for landlords and agents. You can call 0345 464 0079 or send us an email with the address and a few details, and we’ll give you a fixed price before we start.
Is Chadwell St Mary within the area you cover?
Yes, smaller places are covered as well as towns. We work across London and the South East. Just mention lanes, gates or anything else about the route when you book.
Is it worth resealing while the house is still settling?
Where water is getting through, do not wait. Hairline cosmetic gaps can wait until the house has settled.
Can I do it myself?
It depends on the job. High-level, external movement and fire-rated joints are professional jobs.
What do you put in the joint?
Products from Arbo and Everbuild, among others, picked for each joint. We explain the product when we quote.
How long will you be here?
Most jobs take a few hours in a single home, including preparation and clearing up. Your quote will say how long we expect yours to take.
Is there any odour?
That depends on the sealant. Some smell for a while, some hardly at all.
Is the work guaranteed?
Yes: twelve months. If there’s a problem with our work in that time, tell us and we will put it right.

DIY versus a professional finish
The biggest DIY mistake is sealing over old sealant. Silicone doesn’t stick to old silicone, so it peels away and traps moisture behind it. Everything old must be removed first.
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
When to call us in Chadwell St Mary
If plaster or screed was still damp when it was sealed, the bond suffers. On a busy site, joints are not always given time to dry before the sealant goes on.
Common reasons people contact us are:
- New-build shower sealant that has already split
- Gaps behind new kitchen upstands
- Gaps between new skirting and floors
- Gaps opening as the house dries out and settles
If you’ve bought a new home near East Tilbury station, the sealant around baths, showers and frames is worth checking in the first year or two.

- Whether you can choose the colour
- Is the old sealant removed completely?
- What product goes in the joint

What sealant work can’t fix
We will not take on work that won’t last, so these are the limits:
- Disputes or warranty claims with your builder
- Damaged fittings that need replacing
- Cracking that points to a structural problem
If you are not sure, just ring 0345 464 0079 or send us an email and we will give you a straight answer.

Leave it or put it right?
A quick bead over the top of the old sealant can look fine at first, but it won’t bond to the old layer. A lasting seal starts with removing the old one completely. Around Chadwell St Mary, water from a failed joint in an older home can soak into timber and plaster, which is far harder to put right than the sealant itself.
We do not show prices on the website, because the cost depends so much on the job itself. Call for a quick quote.

Looking after it afterwards
Joint life depends on how it’s used and looked after. We suggest:
- Wipe joints with warm soapy water
- Raise failed sealant with the developer while you’re covered
- Photograph failed sealant before it’s redone
- Avoid running a DIY bead over the old one
Watch the joints as the house settles. Hairline gaps can open as timber and plaster dry and can be resealed later.
A seal that splits early is often a sign of movement. Have it resealed, and the tray or bath checked, before it gets worse.
