Your questions about new build mastic in Boarshead
Do you cover smaller places like Boarshead?
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 Eridge station?
Yes. We work for landlords and letting agents as well as homeowners, and several properties can be quoted together. Just phone 0345 464 0079 or email us with the address and what needs doing, and we will give you a clear price.
Can you match the sealant colour to my new kitchen or bathroom?
It depends on the joint: white or clear for most sanitary joints, colours for worktops, floors and frames. We agree the colour before any work starts.
Do you take out the old sealant first?
Yes, every time. New sealant will not bond properly to old, so the joint is cleaned back first.
Why does sealant fail so quickly in new builds?
A new house dries and settles for a year or two, and sealant is often rushed onto dusty, unprimed surfaces. Either can make it fail early.
Can you do plot mastic on a new development?
Yes. We take on second-fix sealant work across new plots. We clean and prime joints properly to keep callbacks down.
What sealant do you use?
Each joint gets the product that suits it. Movement, water and weather all affect the choice, and we’ll tell you what we’re using.
Will you leave a mess?
No. The area is protected while we work and cleaned up afterwards.
How we handle new build mastic in Boarshead
A new build should have a neat, sound bead at every joint. When the finish is smeared, patchy or already cracking, it’s worth putting right early, before water reaches anything behind it. If you’re dealing with sealant work across a run of new homes and cracks appearing as a new home settles, we can put it right, whatever the surface.
Work in a small place like Boarshead just needs the journey and access planning, and the work itself is the same as on any site.

Leave it or put it right?
Water getting past a failed seal in a new build reaches walls and floors that are still settling. Dealing with it early keeps the damage away from ceilings, floors and finishes. In a small place like Boarshead, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
A failed joint rarely gets cheaper to fix by waiting, because water and mould keep working on it. If you’re unsure, ring 0345 464 0079 or email us for an honest opinion and a quote.

Looking after it afterwards
After the cure time, these simple habits help:
- Avoid scourers and strong chemicals on sealant
- Keep water off fresh sealant until it has cured
- Photograph failed sealant before it’s redone
- Put sealant faults on your snagging list early
Watch the joints as the house settles. Hairline gaps can open as timber and plaster dry.
Mould takes hold quickly in sealant that has gaps or lifted edges. Dealing with it before it goes black saves a harder job later.

How the job changes by surface
Plot handovers
Plot mastic is carried out to the developer’s schedule. Joints are prepared properly before sealing.
Show homes
Tired or marked sealant in a show home can be renewed. The old bead comes out and a clean new one goes in.
Should I try it myself first?
Sealing over old silicone is the commonest DIY error. Silicone does not stick to old silicone, so it peels away and traps moisture behind it. All the old material has to come out first.
If you are set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.
