New build mastic across Langley and nearby, with every bit of old sealant taken out first.

What happens on the day
A visit follows a simple pattern: we look at the joints together, protect the area around them, do the work and clear up. Most jobs take a few hours for most snagging lists, longer for a run of plots. For a village or hamlet like Langley, the journey is planned in advance: tell us about narrow lanes, gates, long drives and where we can park. Everything for the job comes with us, so a second trip is avoided where possible.
- First, the list of joints is agreed from your snagging sheet or plot schedule.
- The failed sealant is removed completely.
- We clean out the dust and grit left from the build.
- 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
- Tell us if parking is tricky
- Mention any tricky access
- Clear the area around the work

How we handle new build mastic in Langley
Failed shower seals, gaps along the skirting and messy beads are common items on a new-home snagging list. If you’re still within the builder’s snagging or warranty period, tell them first, and if it is not put right, get in touch with us. Common call-outs are for smeared, uneven beads picked up at snagging and cracks appearing as a new home settles, across windows & doors, show homes and skirting & floors.
Around Langley, older homes often have timber floors that move through the year, which is why skirting and threshold joints need a flexible sealant, not filler.
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 sealant or a professional job?
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is.
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
How to look after the new joints
Aftercare is simple, and it makes a real difference:
- Open a window or run the fan after bathing
- Photograph failed sealant before it’s redone
- Watch for new gaps as the house dries out
- Keep water off fresh sealant until it has cured
Keep photos of the joints and any snagging correspondence with your builder. It’s useful if you need to raise other issues later.
Lifting sealant traps moisture and mould behind it. Dealing with it before it goes black saves a harder job later.
Why act early in Langley
For developers, getting the sealant right first time saves return visits. Snagging visits for failed sealant cost time on every plot and most come down to preparation. Where a wall is exposed, as many are in small places like Langley, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
No two jobs are quite the same, so we quote each one individually. The number of joints, how easy they are to reach and the sealant needed all play a part.

Joints and finishes in Langley homes
Langley is close to the coast. New homes near the sea put their outside mastic to work from day one, so it’s worth checking at snagging. 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.
For new homes near Hamble station, it’s worth checking the sealant early, while snags are still fresh.

FAQs for Langley
Will you come out to Langley?
Yes, smaller places are covered as well as towns. We work across London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Can you help a landlord with a rental near Hamble station?
Yes, rental work is part of what we do. Just phone 0345 464 0079 or send us an email and tell us about the property, and we’ll give you a clear price.
How long will you be here?
Most jobs take anything from a few hours to several days, depending on the number of plots, including the preparation. Your quote will say how long we expect yours to take.
Can you do plot mastic on a new development?
Yes. Second-fix sealing in bathrooms, kitchens, frames and floors is part of what we do. Good preparation keeps snagging to a minimum.
Which products do you use?
Quality sealants from brands including Arbo and Everbuild, picked for each joint. We explain the product when we quote.
Who should fix failed sealant in a new build?
If you are still within the builder’s snagging or warranty period, report it to them first. If they’re slow or the fix doesn’t last, we can help.
Can you reseal over the builder’s sealant?
No. Sealing over old sealant looks fine for a few weeks, then lifts. We remove every bit of the old bead before resealing.
Do I have to be there?
Access is agreed with you when the job is booked. Indoors, that normally means someone at home.
Signs you need new build mastic in Langley
Fresh sealant can be knocked or cut by trades finishing off. If it’s disturbed before curing, the joint can be left weak, and the problem shows up after you move in.
Any of these means the joints need attention:
- Sealant applied over dusty or wet surfaces
- Skirting joints opening in the first winter
- Gaps behind new kitchen upstands
- Smeared, uneven beads picked up at snagging
In and around Langley, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.
