How we handle new build mastic in Olney
Failed shower seals, gaps along the skirting and messy beads are common items on a new-home snagging list. If you are still within the builder’s snagging or warranty period, tell them first, and if it isn’t put right, get in touch with us. We work on bathrooms & en suites, windows & doors and kitchens, and people most often call us about cracks appearing as a new home settles and skirting joints opening in the first winter.
Homes around Olney range from older cottages to newer houses, and their floors range just as widely, each moving in its own way. Skirting and threshold joints need a sealant that suits the floor.
There’s a 12-month guarantee on every job.

Why act early in Olney
A hairline gap at a skirting can wait, but water getting through can’t. If you’re unsure which you have, ring 0345 464 0079 or drop us an email with photos. In a smaller place like Olney, wherever a wall is exposed, a failed outside joint is a real source of damp. Inside, a split seal lets water into floors and panels just as it would anywhere.
What it costs depends on the amount of work, how much old material has to come out and how easy the joints are to reach. We give a clear quote before we start.

Aftercare tips
After the cure time, these simple habits help:
- Use the extractor fan every time you shower
- Avoid running a DIY bead over the old one
- Wait for the cure time before using a resealed shower
- Report sealant problems to your builder during the snagging period
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. After that, putting it right may fall to you.
Common questions in Olney
Will you come out to Olney?
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.
Is new build mastic in Olney guaranteed?
All our work, in Olney and everywhere else, comes with a 12-month guarantee. We’re also fully insured and ARBOMaster approved.
Can tenants book the work?
Of course. Check with your landlord; we can send the quote to them too.
Can you work from my snagging list?
Yes. We often work straight from a snagging list. We’ll go through the sealant items and agree what we will do.
Are you ARBOMaster approved?
Yes. We are an ARBOMaster approved applicator, which is run for the Arbo sealant brand.
Do you work for hotels and businesses?
Yes. We can plan bigger jobs in stages to suit the site.
Can landlords and businesses book you?
Yes, we do. Domestic, commercial and hotel work are all part of what we do.
What do you put in the joint?
It depends on the joint: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. Brands we use include Arbo and Everbuild.
Landlord and commercial work in Olney
In hotels, rooms out of use cost money, so we plan the work room by room around your bookings where we can. Hotel work is part of what we do, alongside homes and businesses.
Failed sealant is one of the commonest items on a check-out report, and it’s quick to put right between tenancies. Several properties can be quoted together.
How it works
Once we are on site, we compare the joints with what we discussed. If we find something unexpected, we talk it through with you first. Most jobs then take anything from a few hours to several days, depending on the number of plots. A visit to Olney is planned like any other: the time, the access and where to park are agreed in advance. If the work is outside, the weather plays a part, as sealant needs a dry surface.
- We go through the snagging list or plot schedule and agree the joints to do.
- The old bead comes out in full, with no layer left behind.
- We clean off dust from the build and prime the surfaces where the product needs it.
- New sealant suited to each joint is applied and tooled neatly.
- Each area is checked and left with its cure time.
Preparing for the visit
- Let us know about earlier repairs to the joints
- Mention any parking rules near the property
- Try not to wet indoor joints just before the visit

Advice
DIY versus a professional finish
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions, and the work is guaranteed for a year.
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
What we’re called out for in Olney
Not every new-build joint gets the right sealant: caulk where water collects, or a rigid product on a moving joint. Both fail early.
It’s worth asking for a quote if you see:
- Shower seals failing in the first year or two
- Gaps behind new kitchen upstands
- Untidy sealant flagged on a snagging list
- Cracks appearing as a new home settles
For jobs in and around Olney, choosing the right material for each joint is as important as a tidy finish.
Questions to ask before booking
- Which colour the sealant will be
- What preparation is included
- What guarantee comes with the work
- Which sealant they’ll use, and why
