How we handle new build mastic in Denton
Snagging sealant properly means taking the failed bead out completely. New silicone won’t bond to old silicone, so the joint is cut out, cleaned, dried and resealed. We work on windows & doors, plot handovers and kitchens, and people most often call us about smeared, uneven beads picked up at snagging and leaking shower tray seals in a new home.
Older homes in small places like Denton often have timber floors that move with the seasons, which is why skirting and threshold joints need a flexible sealant, not filler.
All of our work is guaranteed for twelve months.

What the job involves on each surface
Skirting and floors
Where the floor meets a bath panel or kitchen plinth, the joint keeps mop water out. We seal them with a sealant suited to wet areas.
Plot handovers
Taking time over preparation reduces return visits. We clean out building dust before sealing and primer used where needed.
How it works
When we arrive, we look over the joints with you first, so there are no surprises. Surfaces next to the work are protected before any work begins. Most jobs take a few hours for most snagging lists, longer for a run of plots. In a small place like Denton, access is generally the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- We start by agreeing which joints are on the list, from the snagging sheet or plot schedule.
- We cut out every bit of the failed or messy sealant.
- Each joint is cleaned of dust and grit, then primed if required.
- We apply a sealant that suits each joint and tool it to a neat finish.
- Finally, each room is checked and you’re given the cure time.
How to prepare
- Try not to wet indoor joints just before the visit
- On commercial sites, let us know about site rules
- Mention if the joints have been sealed before
How to get a quote
Getting a quote is simple: tell us what needs doing and where. A few pictures by email make the job easier to understand.
Related advice
Should I try it myself first?
Sealing over old silicone is the commonest DIY error. New silicone won’t bond to old, so it lifts and traps water and mould underneath. All the old material has to come out first.
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.

What affects the cost of new build mastic
Every job gets its own quote. This is what makes a difference:
- Access and height
- Whether there’s mould to deal with
- Any working-time requirements on site
- The number of rooms or windows
A failed joint rarely gets cheaper to fix by waiting. If you are unsure, call 0345 464 0079 or send us an email for an honest opinion and a quote.
What we need to know
When you call or email, these details help:
- Pictures of the joints, sent by email
- Roughly how big the job is
- Where the property is
- Whether it has been sealed before
The more we know about the job, the more useful the quote. Tell us where the job is, what’s wrong and how much there is, and email pictures if that’s easy.
Leave it or put it right?
A tube of sealant from the DIY shop will not fix the cause: grit, unprimed surfaces and old layers underneath. Proper removal and preparation are what make it last. Older cottages and farmhouses around Denton can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
A few things move the cost up or down: how much old sealant there is and how stubborn it is, whether mould needs treating, and whether the work is at height. We take all of that into account in your quote.
Why us?
- Tidy, careful work
- White, clear, grey or coloured to suit, where the product allows
- Arbo and Everbuild products
- A sealant colour to suit the surroundings

Looking after it afterwards
Once the sealant has cured, a few habits help it last:
- Raise failed sealant with the developer while you’re covered
- Avoid scourers and strong chemicals on sealant
- Use the extractor fan every time you shower
- Get a leaking seal dealt with right away
Wipe the sealant with warm soapy water. Avoid abrasive pads and strong solvents as they wear the bead.
Mould takes hold quickly in sealant that has gaps or lifted edges. Dealing with it before it goes black saves a harder job later.
