What happens if it’s left?
Water getting past a failed seal in a new build reaches walls and floors that are still settling. Resealing promptly protects the new finishes around it. Older cottages and farmhouses around Waterbeach can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
Commercial jobs are quoted on the same basis as homes: the amount of work, the access and the products needed. Call for a quick quote and we will explain what it covers.

How we handle new build mastic in Waterbeach
We never seal over a failed new-build bead. New silicone will not bond to old silicone, so the joint is cut out, cleaned, dried and resealed. We work on show homes, skirting & floors and plot handovers, and common reasons people get in touch are worktop and upstand sealant coming away and sealant applied over dusty or wet surfaces.
In a village or hamlet like Waterbeach, new homes are more likely to be a barn conversion or a handful of houses than a big estate. Each still needs its sealant and floor joints finished properly.
Our work is backed for twelve months, in Waterbeach and everywhere else we cover.

What we do, step by step
At the end, we look at the finished work together and explain the cure time. The work normally takes a few hours in a single home, depending on the amount of work. In a small place like Waterbeach, access is normally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We look at why each joint failed, including any movement.
- Old sealant is cut out and the joints cleaned.
- We make sure the joints are dry and prime them if needed.
- New sealant goes in, with baths filled first so they’re at their heaviest.
- The finished joints are checked and the cure times given.
Getting ready for the visit
- On commercial sites, let us know about site rules
- Try not to wet indoor joints just before the visit
- Mention if the joints have been sealed before

How to look after the new joints
Once the sealant has cured, a few habits help it last:
- Raise failed sealant with the developer while you’re covered
- Record problems with dated pictures
- Use the extractor fan every time you shower
- Wipe joints with warm soapy water
Keep the bathroom ventilated, especially in the first year. Run the fan or open a window after bathing to help keep mould away.
Leave a failed new-build seal and water can reach the floor and the ceiling below. Catching it early keeps the fix to the sealant and protects the rest of the house.
Surface by surface
Kitchens
Worktops in new homes can move slightly as the house dries, which opens gaps along the back. We reseal them with a flexible sealant.
Windows and doors
Internal joints between frames and plaster often crack as a new house dries. We remove cracked sealant and apply a flexible one that suits the frame.
New homes and floors in Waterbeach
Rainfall in the South East is lower than in much of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.

Waterbeach: your questions answered
Will you come out to Waterbeach?
Yes. Waterbeach is within the area we cover, which takes in towns, villages and rural addresses. Our work covers London and the South East. Just mention lanes, gates or anything else about the route when you book.
Can you help a landlord with a rental near Chichester station?
Yes, landlords and agents are among the people we work for. Just call 0345 464 0079 or drop us an email with the address and what needs doing, and we’ll give you a clear quote.
Can you reseal over the builder’s sealant?
No. Fresh silicone does not stick to the old layer, so it soon lifts and traps water. We cut the old bead out completely.
How long does the job take?
That depends on the amount of work, but most jobs take anything from a few hours to several days, depending on the number of plots. We will tell you when we quote.
Do I have to be there?
That depends on where the joints are. Inside work needs someone to give us access.
When is the sealant fully cured?
It depends on the product and the conditions. We tell you how long to leave it before we go.
Are you ARBOMaster approved?
Yes. ARBOMaster is the approved applicator scheme for Arbo sealants, and we’re part of it.
Do you take out the old sealant first?
Yes. Sealing over old sealant is the main reason resealing fails early, so we never do it.
Landlord and commercial work in Waterbeach
Businesses can book us for washrooms, kitchens, offices and more. For commercial premises, we can talk through working times when we quote.
Letting agents often deal with us directly. Tell us the address, the job and how access works and we’ll give you a quote.
Can I do it myself?
A careful DIYer can reseal a simple joint, 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.
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
