FAQs for Dunsden Green
I let a flat near Reading station. Can you help?
Yes, landlords and agents are among the people we work for. Just ring 0345 464 0079 or drop us an email with the address and what needs doing, and we will give you a clear quote.
Do you cover smaller places like Dunsden Green?
Yes, Dunsden Green is covered. Our work covers London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.
Are you ARBOMaster approved?
Yes. We are approved under the ARBOMaster scheme, the approved applicator scheme for Arbo sealants.
Do you do commercial work?
Yes, regularly. We can plan bigger jobs in stages.
Do you work for developers?
Yes. We take on second-fix sealant work across new plots. Good preparation keeps snagging to a minimum.
Is it worth trying it myself?
That depends on the joint. High-level, external movement and fire-rated joints are professional jobs.
Do the sealants smell?
There can be a smell while the sealant cures, which fades as it sets. Opening a window helps.
Can new sealant go on top of the old bead?
No. The old sealant is cut out fully, then clean and prime the joint, and a new bead applied.
New build mastic in Dunsden Green, done properly
Dust is the enemy of new-build sealant. Each joint is cleaned of dust and primed where the product calls for it, so the sealant actually sticks instead of bonding to the dust. We work on skirting & floors, plot handovers and show homes, and the jobs we see most are untidy sealant flagged on a snagging list and joints pulling apart as timber shrinks.
Work in a small place like Dunsden Green just needs the journey and access planning, and the work itself is the same as on any site.
We stand behind the work with a one-year guarantee, so you’re not left on your own once the job is done.

Do you need new build mastic in Dunsden Green?
Fresh sealant can be knocked or cut by trades finishing off. If it’s disturbed before curing, the joint can be left weak.
Keep an eye out for these signs:
- Sealant work across a run of new homes
- Worktop and upstand sealant coming away
- Smeared, uneven beads picked up at snagging
- Cracked caulk along new skirting
If you’ve bought a new home near Reading station, the sealant around baths, showers and frames is worth checking in the first year or two.

Different surfaces, different methods
Skirting and floors
As timber and screed dry, skirting and floors shift. We use a flexible product rather than caulk in a colour to suit.
Show homes
We can refresh show-home sealant that has discoloured or been knocked. We cut it out and reseal neatly.
Leave it or put it right?
Running a new bead over the builder’s sealant might look tidy for a few weeks, but it cannot bond to what’s underneath. A lasting seal starts with removing the old one completely. Older cottages and farmhouses around Dunsden Green can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
There are no prices on our website, because the cost depends so much on the job itself. Call for a quick quote.

Quotes for new build mastic in Dunsden Green
Jobs vary more than people expect. The main factors:
- The type of sealant required
- Whether there’s mould to deal with
- The number and length of the joints
- How many areas need sealing
A few things move the cost up or down: the old material and how easily it comes out, whether mould needs treating, and whether we need extra access for height. Your quote takes all of that into account.
What we need to know
The more you tell us, the more accurate the quote. When you get in contact, it helps to mention:
- What the problem is, such as mould, gaps, leaks or cracking
- How many joints, rooms or windows are involved
- If someone has resealed it before
- Photos by email, if that is easy

The process
A visit follows a simple pattern: we look at the joints together, protect the area around them, carry out the job and clear up. It usually takes a few hours for most snagging lists, longer for a run of plots. Somewhere like Dunsden Green needs a little journey planning: 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.
- We start by going through the snagging items or plot schedule with you.
- The failed sealant is removed completely.
- Joints are vacuumed and cleaned of building dust.
- Primer goes on where the surface and product need it, then the new sealant.
- Each bead is tooled and the cure times explained.
Getting ready for the visit
- Clear items away from the joints we’re working on
- Tell us about any water getting in
- Try not to wet indoor joints just before the visit

Related advice
Looking after it afterwards
Aftercare is simple, and it makes a real difference:
- Follow the cure time we give you
- Look at the sealant regularly in the first couple of years
- Avoid running a DIY bead over the old one
- Use the extractor fan every time you shower
Photograph failed sealant before it’s redone and keep the builder’s replies. It’s useful if you need to raise other issues later.
Report failed sealant to the builder while you’re in the snagging period. Once it ends, the repair may be down to you.
Honest limits
New sealant can’t fix everything, and we’d rather say so up front. It will not solve:
- Leaking fittings rather than failed sealant
- Structural cracks in walls or ceilings
- Movement caused by a poorly fitted tray or bath
Not sure which it is? You can phone 0345 464 0079 or send us an email and we will tell you honestly.
