Woodham questions
Do you cover Woodham for new build mastic?
Yes, Woodham is within the area we cover. Our work covers London and the South East. Just call 0345 464 0079 or send us an email with a few details of the job, and we’ll give you a clear quote.
Will you come out to Woodham?
Yes, we do. We work across London and the South East, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
Will you leave a mess?
Very little: the area around the joints is protected first, and we tidy up before we go.
How do I get a quote for new build mastic in Woodham?
Size, access and the old material all affect the cost. Ask us for a quote.
Can you work from my snagging list?
Yes. Send it with pictures and we’ll quote for the sealant items. If something isn’t sealant, we’ll say so.
Where is Mr Mastic based?
We’re a Crawley-based firm. Our area covers South East England, London and Scotland.
Are you fully insured?
Yes, we are fully insured for every job we do.
Can new sealant go on top of the old bead?
No. New silicone will not bond to old silicone, so sealing over the top fails quickly. The old sealant always comes out first.
About our new build mastic in Woodham
Snagging sealant properly means taking the failed bead out completely. New silicone won’t bond to old silicone, so it all comes out before we clean, dry and reseal. If you have sealant work across a run of new homes and smeared, uneven beads picked up at snagging, we can put it right.
In and around Woodham, floors range from older timber boards to tiles and newer finishes, each moving in its own way. The sealant at skirtings and thresholds has to suit the floor it meets.
A 12-month guarantee comes with the work, just as it does everywhere we cover.

Quotes for new build mastic in Woodham

Combining jobs into one visit is generally more efficient than separate visits, so tell us about everything that needs sealing. We will give you a clear quote for the lot.

Photos by email are helpful but not essential. Please mention:
- If someone has resealed it before
- What’s wrong with the joints now
- Any access issues, like height or stairs

To get a quote, ring 0345 464 0079 or send us an email and tell us where the job is and what the problem looks like. You will have a clear quote before any work starts.
Why it’s worth doing now in Woodham
Resealing everything on a snagging list in one visit is usually simpler than chasing joints one at a time. You get one visit and one clear quote for the lot. In an older home around Woodham, damp from a failed joint can get into timber and plaster, and that is a much bigger job than renewing the sealant.
A few things move the cost up or down: the old material and how easily it comes out, any mould to treat, and whether we need extra access for height. We take all of that into account in your quote.

Looking after it afterwards
Aftercare is simple:
- Ventilate bathrooms well, especially in the first year
- Avoid running a DIY bead over the old one
- Wait for the cure time before using a resealed shower
- Wipe joints with warm soapy water
Watch the joints as the house settles. Small gaps can appear as the house dries.
Do not let the snagging period run out with sealant problems unreported. After that, putting it right may fall to you so report it promptly.
Should I try it myself first?
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
How the job changes by surface
Kitchens
Sink joints are wet all the time. We use a sealant suited to kitchens suited to the job.
Windows and doors
Internal joints between frames and plaster often crack as a new house dries. We remove cracked sealant and apply a flexible one that suits the frame.
New build mastic around Woodham
