What we do, step by step
There is not much for you to do on the day. Point us to the joints and we’ll get on with it. The work itself takes anything from a few hours to several days, depending on the number of plots, including the tidy-up. Somewhere as small as Cottonworth, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- First, the list of joints is agreed from your snagging sheet or plot schedule.
- The failed sealant is removed completely, with no layer left behind.
- Joints are vacuumed and cleaned of building dust.
- We prime where needed and apply a sealant suited to each joint.
- We tool every joint neatly and tell you when each area can be used.
Preparing for the visit
- Mention if the joints have been sealed before
- Let us know if you’ve seen damp or leaks
- Mention any sign-in or site rules at work premises

It all starts with a short chat. Tell us what’s wrong, where it is and how much there is, and we will explain how we’d tackle it. When it suits you, call 0345 464 0079 or send us an email.
Advice
About our new build mastic in Cottonworth
If your new home has a leaking shower seal, open skirting joints or untidy sealant, we can help. 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. If you have untidy sealant flagged on a snagging list and frame joints opening as the plaster dries, we can put it right, on plot handovers, bathrooms & en suites and skirting & floors alike.
Older homes in small places like Cottonworth often have timber floors that move with the seasons, which is why skirting and threshold joints need a flexible sealant, not filler.
Every job is covered by a 12-month guarantee.

Questions from Cottonworth
Do you cover smaller places like Cottonworth?
Yes, Cottonworth is covered. We work across London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.
Do you work for landlords with property near Andover station?
Yes, we work for landlords and letting agents. You can call 0345 464 0079 or email us with the address and a few details, and we’ll give you a fixed price before work begins.
Can you work from my snagging list?
Yes. Snagging lists are a common starting point for us. We agree the sealant items with you before work begins.
Where are you based?
Our base is Crawley, with over 20 years’ experience. Our area covers South East England, London and Scotland.
Do the sealants smell?
That depends on the sealant. Some smell for a while, some hardly at all, and any smell fades as they cure.
Should I go to my builder first?
While the snagging or warranty period runs, the builder should be your first contact. If they’re slow or the fix doesn’t last, we can help.
Can I do it myself?
Sometimes. Preparation is everything: all the old sealant out, and a clean, dry joint. We can always put it right if it fails.
Do you work for hotels and businesses?
Yes. We have worked for hotels, offices and other businesses and we’re fully insured.
What sealant work cannot fix
A few problems are outside what sealant work can do:
- Disputes or warranty claims with your builder
- Settlement cracks that need a surveyor
- Baths and trays that move too much for sealant to cope with
Not sure which it is? You can phone 0345 464 0079 or send us an email and we will tell you honestly before booking.

What else we do in Cottonworth
Why deal with it now?
Water getting past a failed seal in a new build reaches walls and floors that are still settling. Dealing with it early keeps the damage away from ceilings, floors and finishes. Older cottages and farmhouses around Cottonworth can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
What you pay reflects the work, not guesswork. That is why we ask about the job first and send you a clear quote before any work starts.

Can I do it myself?
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.
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 fails, we can still redo it.

Keeping the joints in good condition
Once the sealant has cured, a few habits help it last:
- Wipe joints with warm soapy water
- Keep water off fresh sealant until it has cured
- Keep pictures and emails about snagging items
- Avoid running a DIY bead over the old one
Clean the sealant with a mild detergent and a soft cloth. Keep scourers and harsh chemicals off it as they wear the bead.
Mould takes hold quickly in sealant that has gaps or lifted edges. Resealing before mould gets in keeps the job straightforward.
