Why deal with it now?
It often makes sense to do all the sealant items on a snagging list together. It’s one visit, one quote and one set of cure times to plan around. Around Oakhanger, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
We don’t show prices on the website, because the cost depends so much on the job itself. Call for a quick quote and we’ll talk you through it.

New build mastic in Oakhanger
Building dust is behind a lot of failed new-build sealant. We clean every joint thoroughly and prime where the surface and product need it, so the new bead bonds properly instead of bonding to the dust. We work on plot handovers, show homes and windows & doors, and the jobs we see most are cracked caulk along new skirting and untidy sealant flagged on a snagging list.
For a small place like Oakhanger, the journey and access are planned in advance, and the work itself is the same as on any site.
Our work is backed for twelve months, and the guarantee is the same wherever you are.

What the job involves on each surface
Plot handovers
We work through plots to your schedule, sealing each room ready for handover. Joints are prepared properly before sealing.
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 in a matching colour.

From a single let to a portfolio, you get the same standard of work: old sealant fully removed, joints prepared properly and a one-year guarantee.
We also work for businesses, from offices to washrooms and kitchens. For commercial premises, we can talk through working times when we quote.
Can I do it myself?
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.
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 doesn’t work out, we can still put it right.
How it works
Before we leave, we go over the finished joints with you and tell you how long to leave it. The work normally takes a few hours for most snagging lists, longer for a run of plots, depending on the size of the job. For a village or hamlet like Oakhanger, the journey is planned in advance: let us know about lanes, gates and parking. We bring what the job needs, so it can be finished in one trip where possible.
- We look at why each joint failed, including any movement.
- We remove the failed sealant and clean the joints.
- Joints are dried and primed where the product calls for it.
- Baths are filled with water, then the new sealant is applied.
- The finished joints are checked and the cure times given.
How to prepare
- Tell us if parking is tricky

It all starts with a short chat. Tell us what’s wrong, where it is and how much there is, and we will talk you through what we’d do. When it suits you, call 0345 464 0079 or email us.
Advice
What affects the quote in Oakhanger
You’ll get a clear quote before any work starts. It’s based on:
- Whether the work is at height
- Whether there’s mould to deal with
- Whether old sealant or filler has to be cut out
- When we can work, for business premises
Combining jobs into one visit generally makes better use of the time than several visits, so it’s worth mentioning everything you’d like done. We’ll send you a clear quote for the lot.
Helping us quote
The more you tell us, the more accurate the quote. When you ask for a quote, tell us:
- Any previous sealing or DIY work
- The address or postcode of the job
- How we’d reach the joints
- The rough size of the job
We don’t publish a price list, because every job is different. Instead, your job gets its own clear quote. To arrange one, phone 0345 464 0079 or send us an email.
When to call us in Oakhanger
Once people move in, baths and trays take weight and bed down. If a bath wasn’t filled when it was sealed, the bead is stretched the first time it’s used and can tear.
Look out for these signs:
- Second-fix sealing on new plots
- Untidy sealant flagged on a snagging list
- Cracked caulk along new skirting
- Gaps opening as the house dries out and settles
In and around Oakhanger, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.
