New build mastic in Little Barrington
Building dust is behind a lot of failed new-build sealant. We clean every joint thoroughly and prime where the surface and product need it, so the sealant actually sticks instead of bonding to the dust. If you have leaking shower tray seals in a new home and skirting joints opening in the first winter, we can help, whatever the surface.
Around Little Barrington, older homes often have timber floors that move through the year, so skirting and threshold joints need a flexible sealant rather than a rigid filler.
Each job carries a 12-month guarantee, whatever its size.

How the visit works
A visit follows a simple pattern: we check the joints, mask and protect the surrounding surfaces, carry out the job and tidy away. It normally takes anything from a few hours to several days, depending on the number of plots. Somewhere as small as Little Barrington, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- 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.
- Baths are filled with water, then the new sealant is applied.
- The finished joints are checked and the cure times given.
How to prepare
- Mention if the joints have been sealed before
- Move anything stored near the joints
- Mention any parking rules near the property

When it is not the sealant
Honest advice matters more to us than a booking, so here’s what new sealant will not do:
- Your warranty claim itself, which is between you and the builder
- Leaking fittings rather than failed sealant
- A tray or bath that isn’t properly supported, until it’s fixed
Not sure which it is? You can call 0345 464 0079 or send us an email and we’ll tell you honestly.

Should I try it myself first?
The biggest DIY mistake is sealing over old sealant. Silicone does not stick to old silicone, so it peels away and traps moisture behind it. Everything old must be removed first.
If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it doesn’t work out, we can still put it right.
Looking after it afterwards
Simple care keeps the joints in good condition. Our advice:
- Follow the cure time we give you
- Get a leaking seal dealt with straight away
- Avoid scourers and strong chemicals on sealant
- Ventilate bathrooms well, especially in the first year
Wipe the sealant with warm soapy water. Avoid abrasive pads and strong solvents as they wear the bead.
Lifting sealant traps moisture and mould behind it. Dealing with it before it goes black saves a harder job later.
Joints and finishes in Little Barrington homes
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.
For jobs in and around Little Barrington, choosing the right material for each joint is as important as a tidy finish.

Leave it or put it right?
It often makes sense to do all the sealant items on a snagging list together. It’s one visit, one quote and one set of cure times for the lot. In a small place like Little Barrington, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
What it costs depends on the amount of work, how hard the old material is to remove and how easy the joints are to reach. We give a clear quote before any work starts, so you know where you stand.
Why us?
- Approved under the ARBOMaster scheme
- Full insurance on every job
- A sealant colour to suit the surroundings
- Every job guaranteed for a year

Signs you need new build mastic in Little Barrington
Sealant applied onto damp surfaces does not bond well. On a busy site, joints are not always given time to dry.
The problems people normally mention when they call include:
- Shower seals failing in the first year or two
- Cracked sealant around new window and door frames
- Sealant that never bonded to the surface
- Gaps between new skirting and floors
In and around Little Barrington, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.

What guarantee comes with new build mastic in Little Barrington?

How long does new build mastic 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 give you a better idea when we quote.
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 can reseal it properly.
Do you work for hotels and businesses?
Yes. Larger jobs can be planned room by room or area by area.
Do you remove the old sealant?
Yes, every time. New silicone does not stick to old silicone, so any old material comes out before anything new goes in.
Can tenants book the work?
Yes, but check with your landlord or agent first. Many landlords are glad to have it sorted.
Is it normal for sealant to crack in a new home?
It’s common, and there are usually two reasons: the house moving as it dries, and sealant that never bonded properly. Cutting it out and resealing properly fixes both.
