Why it’s worth doing now in Widford
Sealant done properly at handover means fewer callbacks. Every return visit for a failed seal takes time, and they’re avoidable with good preparation. Older cottages and farmhouses around Widford can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
What you pay reflects the work, not a rough estimate. That is why we ask a few questions first.

How we handle new build mastic in Widford
We never seal over a failed new-build bead. New silicone won’t bond to old silicone, so it all comes out before we clean, dry and reseal. If you have cracks appearing as a new home settles and worktop and upstand sealant coming away, we can help, whatever the surface.
Older homes in small places like Widford often have timber floors that move with the seasons, which is why skirting and threshold joints need a flexible sealant, not filler.

Surface by surface
Plot handovers
Good preparation at handover saves snagging later. Dust from the build is removed first and prime where the product needs it.
Bathrooms and en suites
Shower trays in new homes often move slightly in the first year. The joint is stripped back before the new bead goes in.
Honest limits
In fairness, some problems need a different trade:
- Cracked trays, tiles or worktops
- Settlement cracks that need a surveyor
- Leaking fittings rather than failed sealant

Widford questions
Will you come out to Widford?
Yes, Widford is covered. Our work covers London and the South East, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
Can you help a landlord with a rental near Harlow Town station?
Yes. We work for landlords and agents as well as householders, and several properties can be quoted together. You can phone 0345 464 0079 or send us an email with the details for a clear quote.
Do you work for developers?
Yes. We carry out plot mastic and second-fix sealing for builders and developers. Send the schedule and any specification and we will give you a quote.
Can new sealant go on top of the old bead?
No. We always remove the existing bead, the joint cleaned and primed where needed, before resealing.
Is there any odour?
That depends on the sealant. Some products have a noticeable smell, others very little, and any smell fades as they cure.
Do I have to be there?
That depends on where the joints are. For work indoors, someone needs to let us in, while outside work can sometimes be arranged differently.
Should I wait before resealing?
It depends on whether water is getting through. A leaking shower or bath seal should be redone straight away, but cosmetic gaps can wait for movement to slow.
Do you remove the old sealant?
Yes, always, and completely. New sealant will not bond properly to old, so the joint is cleaned back first.
When to call us in Widford
The first winter with the heating on dries a new home quickly. Gaps open along skirting, frames and worktops.
If you can see any of these, it’s time to have the joints looked at:
- Leaking shower tray seals in a new home
- Cracked sealant around new window and door frames
- Plot mastic for developers ahead of handover
- Cracked caulk along new skirting
For new homes near Harlow Town station, it’s worth checking the sealant early, while snags are still fresh.
What your quote should include
- Who does the work, and how experienced they are
- Whether all the old sealant comes out first
- How hidden problems are handled
- Whether the sealant suits the joint
How to look after the new joints
How long the joints last depends on use and care. Here’s what we suggest:
- Get a leaking seal dealt with right away
- Avoid running a DIY bead over the old one
- Wait for the cure time before using a resealed shower
- Use the extractor fan every time you shower
Keep an eye on the joints over the first couple of years. Hairline gaps can open as timber and plaster dry.
If a shower tray or bath seal splits in the first year, look for movement. Getting it resealed properly, and any movement checked, stops it recurring.

Should I try it myself first?
If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it does not work out, we can still put it right.
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and does not move well, and getting the depth right matters as much as the look.
