About our new build mastic in Steephill
Failed shower seals, gaps along the skirting and messy beads are common items on a new-home snagging list. While the builder’s snagging or warranty period runs, report it to them first and if that stalls, we can do it. If you’re dealing with leaking shower tray seals in a new home and cracked caulk along new skirting, we can put it right.
Work in a small place like Steephill just needs the journey and access planning, and the work itself is the same as on any site.
We guarantee the work for a year. If there’s a problem with our work within the year, let us know and we will sort it.

DIY versus a professional finish
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
Sealing over old silicone is the commonest DIY error. New silicone won’t bond to old, so it peels away and traps moisture behind it. All the old material has to come out first.

New homes and floors in Steephill
Steephill is close to the coast. New homes near the sea put their outside mastic to work from day one, so any gaps are best picked up early. Rainfall in the South East is lower than in much of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
If you’ve bought a new home near Shanklin station, the sealant around baths, showers and frames is worth checking in the first year or two. Around Steephill, as everywhere, new build mastic is only as good as the preparation behind it.

Surface by surface
Show homes
Tired or marked sealant in a show home can be renewed. We cut it out and reseal neatly.
Plot handovers
Good preparation at handover saves snagging later. We clean out building dust before sealing and primer used where needed.
When something else is needed
It helps to know what we cannot do too:
- Plumbing faults behind the sealant
- Damaged fittings that need replacing
- Baths and trays that move too much for sealant to cope with
If you are not sure, just ring 0345 464 0079 or email us and we’ll give you a straight answer.
Joints and surfaces we work on
- Kitchens
- Plot handovers
- Skirting & floors
- Windows & doors
- Show homes
- Bathrooms & en suites
The process
Once we are on site, we compare the joints with what we discussed. If anything is different, we explain it before carrying on. After that, the work takes a few hours for most snagging lists, longer for a run of plots. In a small place like Steephill, access is usually the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- First we work through your snagging list or plot schedule with you.
- The old bead comes out in full, with no layer left behind.
- We clean off dust from the build and prime the surfaces where the product needs it.
- We apply a sealant that suits each joint and tool it to a neat finish.
- We check every joint and tell you how long each needs to cure.
Before we arrive
- Tell us if parking is tricky
- Where the joints are inside, avoid wetting them before we arrive
- Plan for the work area to be out of bounds to pets and children

Questions from Steephill
Is Steephill within the area you cover?
Yes, Steephill is covered. We work across London and the South East, from towns to the smallest places. Longer journeys are simply planned in advance.
I let a flat near Shanklin station. Can you help?
Yes, rental work is part of what we do. You can ring 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.
What sealant do you use?
It depends on the joint: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. We use products from Arbo and Everbuild.
Is it worth resealing while the house is still settling?
If the seal has failed and water is getting in, do it now. Hairline cosmetic gaps can wait until the house has settled.
Do you do commercial work?
Yes. Larger jobs can be planned room by room or area by area to suit the site.
Why has my new-build shower seal failed already?
Cracking in the first couple of years is common. Poor preparation at handover adds to it.
Do you guarantee your work?
Yes, for a year. If there’s a problem with our work in that time, tell us and we will put it right.
Do I have to be there?
That depends on where the joints are. Inside work needs someone to give us access, and for outside work we will agree access with you when we book.
How to look after the new joints
Simple care keeps the joints in good condition. Our advice:
- Do not wait for the house to settle if water is getting through
- Avoid scourers and strong chemicals on sealant
- Wait for the cure time before using a resealed shower
- Ventilate bathrooms well, especially in the first year
Wipe the sealant with warm soapy water. Keep scourers and harsh chemicals off it as they wear the bead.
A seal that splits early is often a sign of movement. Have it resealed, and the tray or bath checked, before it gets worse.
What affects the quote in Steephill
Jobs vary more than people expect. The main factors:
- Whether old sealant or filler has to be cut out
- The size of the job
- Which sealant suits the joint
- Whether the work is at height
What you pay reflects the work, not a rough estimate. That’s why we ask about the job first and agree the price before starting.
What to tell us for a quote
To help us quote quickly, let us know:
- If someone has resealed it before
- The problem you’ve noticed
- Any access issues, like height or stairs
- The rough size of the job
Asking for a quote is easy: let us know the job and the location, and roughly how big it is. A few pictures by email make the job easier to understand, and we will take it from there.
Why it’s worth doing now in Steephill
For developers, getting the sealant right first time saves return visits. Every return visit for a failed seal takes time, and they’re avoidable with good preparation. Older cottages and farmhouses around Steephill can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
Rather than a set price list, we look at what your job involves: the amount of work, the old material and the access. You’ll know the price before we begin.
