DIY versus a professional finish
The biggest DIY mistake is sealing over old sealant. Silicone doesn’t stick to old silicone, so it lifts and traps water and mould underneath. All the old material has to come out first.
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions.
New build mastic in Midgham, done properly
Across Midgham, we work for both new-home owners and the builders handing those homes over. One shower or a whole phase of plots, the method does not change: remove, clean, prime where needed, then a neat new bead. We’re often asked to deal with gaps opening as the house dries out and settles and second-fix sealing on new plots, on plot handovers, windows & doors and skirting & floors.
Around Midgham, 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.

Common questions in Midgham
Can you help a landlord with a rental near Midgham station?
Yes, landlords and agents are among the people we work for. You can call 0345 464 0079 or send us an email with the details for a clear quote.
Will you come out to Midgham?
Yes. Midgham is within the area we cover, which takes in towns, villages and rural addresses. Our work covers London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
What does new build mastic cost?
The cost depends on the size of the job, access and how much old sealant has to come out. Ask us for a quote.
When is the sealant fully cured?
That depends on the sealant used, so follow the cure time we give you.
Do you take on second-fix sealing for builders?
Yes. We take on second-fix sealant work across new plots. Good preparation keeps snagging to a minimum.
Do I have to be there?
We need access to the joints, so we will agree that with you when we book. For inside work, that normally means someone being in.
Are you insured?
Yes. We’re fully insured, and we have been doing sealant work for more than 20 years.
Will it make a mess?
Not at all. The area is protected while we work and cleaned up afterwards.
How to look after the new joints
Joint life depends on how it’s used and looked after. Here’s what we suggest:
- Photograph failed sealant before it’s redone
- Use the extractor fan every time you shower
- Do not seal over failed sealant yourself
- Look at the sealant regularly in the first couple of years
Don’t stand on the bath edge or the lip of the tray. If a bath or tray moves when you stand in it, get it looked at.
If a shower tray or bath seal splits in the first year, look for movement. Getting it resealed properly, and any movement checked, stops it recurring.
Different surfaces, different methods
Plot handovers
Developers can send the plot schedule and specification. Sealant work across the plot is covered to the agreed spec.
Bathrooms and en suites
Trays and baths in new builds settle as they’re used. We reseal once the old bead is fully out and baths are filled before sealing.
What we can’t put right
In fairness, some problems need a different trade:
- Settlement cracks that need a surveyor
- Plumbing faults behind the sealant
- A tray or bath that is not properly supported, until it’s fixed
If in doubt, ring 0345 464 0079 or email us and we will say what we think.

How we quote for new build mastic
For a quick quote, just ask. The main things that affect it are:
- Access and height
- The number of rooms or windows
- Mould in or behind the old joints
- Whether old sealant or filler has to be cut out
Rather than a set price list, we price the job in front of us: how many joints, what’s in them now and how we reach them. You’ll know the price before we begin.
Helping us quote
What to tell us when you ask for a quote:
- Pictures of the joints, sent by email
- Roughly how big the job is
- Where the job is, and your postcode
- The problem you’ve noticed

Signs you need new build mastic in Midgham
The wrong product is sometimes used in the wrong place: decorators’ caulk in a wet area, or a stiff sealant where there’s movement. Neither lasts long.
Any of these means the joints need attention:
- Skirting joints opening in the first winter
- Shower seals failing in the first year or two
- Cracks appearing as a new home settles
- Beads laid onto grit and dust from the build
For new homes near Midgham station, it’s worth checking the sealant early, while snags are still fresh.
Questions to ask before booking
- Which sealant they’ll use, and why
- When the joint can take water or movement
- How the colour is chosen
- Whether they’re fully insured

What we do, step by step
Once we are on site, we compare the joints with what we discussed. If we find something unexpected, we talk it through with you first. Most jobs then take a few hours for most snagging lists, longer for a run of plots. Somewhere as small as Midgham, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We start by going through the snagging items or plot schedule with you.
- Every bit of the old builder’s sealant is cut out, with no layer left behind.
- 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
- Let us know about earlier repairs to the joints
- Move anything stored near the joints
- Tell us about any water getting in
