New build mastic in Guestling Green, done properly
We never seal over a failed new-build bead. Fresh silicone can’t bond to the old layer, so the joint is cut out, cleaned, dried and resealed. If you have skirting joints opening in the first winter and worktop and upstand sealant coming away, we can put it right, whatever the surface.
Work in a small place like Guestling Green just needs the journey and access planning, and once on site, the job is the same as anywhere.
Each job carries a 12-month guarantee, large or small.

Questions from Guestling Green
Will you come out to Guestling Green?
Yes, we do. We work across London and the South East, from towns to the smallest places. Longer journeys are simply planned in advance.
Can you help a landlord with a rental near Three Oaks station?
Yes, rental work is part of what we do. You can call 0345 464 0079 or drop us an email with the address and a few details, and we will give you a fixed price before work begins.
How long will you be here?
That depends on the amount of work, but most jobs take a few hours in a single home. We’ll tell you when we quote.
What information do you need?
A short description and the location. If we need more, we’ll ask.
Is there a guarantee?
Yes: twelve months. If there’s a problem with our work in that time, tell us and we’ll put it right.
Should I go to my builder first?
Report it to the builder first while you’re covered. Once that is done, or if they won’t put it right, we will cut it out and reseal it.
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.
Do you take out the old sealant first?
Yes. All of the old material is cut out and the joint cleaned.
Honest limits
A few problems are outside what sealant work can do:
- Leaking fittings rather than failed sealant
- Your warranty claim itself, which is between you and the builder
- Structural cracks in walls or ceilings
Not sure which it is? You can ring 0345 464 0079 or send us an email and we will tell you honestly.
Surfaces we seal
- Windows & doors
- Skirting & floors
- Plot handovers
- Show homes
- Bathrooms & en suites
- Kitchens
How to look after the new joints
How long the joints last depends on use and care. Here’s what we suggest:
- Raise failed sealant with the developer while you’re covered
- Photograph failed sealant before it’s redone
- Wait for the cure time before using a resealed shower
- Open a window or run the fan after bathing
Follow the cure time we give you before the area gets wet. Most silicones need around a day.
Leave a failed new-build seal and water can reach the floor and the ceiling below. Early resealing keeps the job small and protects the rest of the house.
Joints and finishes in Guestling Green homes
Guestling Green is close to the coast. Plot mastic on new homes near the coast takes more weather than it would inland, so it’s worth checking at snagging. Compared with the north and west, the South East gets less rain, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.

What we are called out for in Guestling Green
Sealant is often one of the last jobs before handover. Joints are not always cleaned of dust or primed, and the sealant sits on grit instead of the surface.
Look out for these signs:
- Smeared, uneven beads picked up at snagging
- Sealant that never bonded to the surface
- Plot mastic for developers ahead of handover
- Gaps between new skirting and floors
If you’ve bought a new home near Three Oaks station, the sealant around baths, showers and frames is worth checking in the first year or two.
What your quote should include
- What the cure time is
- Which colour the sealant will be
- Whether they’re fully insured
- Whether they seal over old material or remove it

What else we do in Guestling Green
Why act early in Guestling Green
If you are still in the builder’s snagging or warranty period, ask them to put it right first. If it’s slow, or the same joint keeps failing, a proper reseal from a specialist is the next step. In a small place like Guestling Green, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
We don’t show prices on the website, because each job is priced on what it involves. For a quick quote, please call 0345 464 0079 or send us an email and we’ll talk you through it.
