How we handle new build mastic in Eastleigh
Developers send us the plot schedule and we work through it. We seal bathrooms, kitchens, windows, doors and skirting so plots are ready to hand over using the right product for each joint. If you’re dealing with cracked caulk along new skirting and second-fix sealing on new plots, we can help.
Shops and business units around Eastleigh have floors that see a lot of traffic. Threshold and floor joints are best resealed before their edges start breaking away.
The work is covered for a year after we finish. If anything is not right with it, call 0345 464 0079 or drop us an email.
Should I try it myself first?
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
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. Everything old must be removed first.
Why deal with it now?
A quick bead over the top of the old sealant can look fine at first, but it cannot bond to what’s underneath. A lasting seal starts with removing the old one completely. Draughts from a gap round a frame, damp under a sill or water behind a bath panel all start small, and they’re far easier to fix early.
Every job is a little different, so we quote each one individually. Size, access and the product the joint needs all play a part, and we’ll explain the quote if you ask.

What affects the cost of new build mastic
The quote reflects the job in front of us. We take into account:
- Whether old sealant or filler has to be cut out
- The product the joint needs
- Mould in or behind the old joints
- The size of the job
Leaving a failed joint normally makes the job bigger, not smaller. If you are not sure whether it needs doing, phone 0345 464 0079 or send us an email for an honest opinion and a quote.

Does someone need to be in?
If the work is inside, we need someone to let us in. Once we’ve agreed the job, you don’t need to watch us work.
Can I add another job to the visit?

Will you leave a mess?
Tidy work is part of the job. We protect what’s around the joints, and the area is left clean when we finish.
Can you reseal over the builder’s sealant?
No. The old sealant is cut out fully, then clean and prime the joint, before resealing.

How it works
Most of a good job is in the preparation, so that is where we spend the time. Joints are cleaned back and dried before anything new goes in. In total, it usually takes anything from a few hours to several days, depending on the number of plots. For a job in Eastleigh, we need access to where the work is and somewhere nearby to park. If the job is outside, mention gates, side access and anything above ground floor.
- We start by going through the snagging items or plot schedule with you.
- Every bit of the old builder’s sealant is cut out down to clean surfaces.
- Joints are vacuumed and cleaned of building dust.
- Primer goes on where the surface and product need it, then the new sealant.
- We tool every joint neatly and tell you when each area can be used.
Before we arrive
- On commercial sites, let us know about site rules
- Clear items away from the joints we’re working on
- Tell us about access, such as stairs, a lift or high-level joints

Advice
Common problems we fix in Eastleigh
Not every new-build joint gets the right sealant: caulk where water collects, or a rigid product on a moving joint. Both fail early.
The most common problems we see are:
- Shower seals failing in the first year or two
- Untidy sealant flagged on a snagging list
- Gaps opening as the house dries out and settles
- Sealant work across a run of new homes
For new homes near Eastleigh station, it’s worth checking the sealant early, while snags are still fresh.
Before booking anyone
- What product goes in the joint
- When the joint can take water or movement
- What happens if the job turns out different
- Whether they’re fully insured
Landlord and commercial work in Eastleigh
A neglected joint can let water reach the structure, which matters even more when someone else lives there. Resealing at the right time is simple maintenance that we can handle for you.
In hotels, rooms out of use cost money, so we plan the work room by room around your bookings where we can. Hotel work is part of what we do, alongside homes and businesses.
When it isn’t the sealant
Before booking, it’s worth knowing the limits:
- Leaks from pipes, valves or wastes, which need a plumber
- Structural cracks in walls or ceilings
- Disputes or warranty claims with your builder
If you are not sure, just call 0345 464 0079 or drop us an email and we will give you a straight answer.
