Remedial sealant for homes and businesses in New Marston
Decorators’ caulk in a shower, bathroom silicone on a window, a rigid filler in a movement joint will not last, however tidy it looks. Out it comes, and in goes a sealant suited to the job. We work on expansion joints, leaking tray & enclosure joints and failed movement joints, and the jobs we see most are thick, messy sealant smeared over tiles and decorators’ caulk around a bath or shower.
In a smaller place like New Marston, homes are mostly houses and bungalows rather than flats, some older and some much newer. Sealant and grout wear out here just as they do in a big town.
We stand behind the work with a 12-month guarantee.

What happens on the day
Every visit runs the same way: we look at the joints together, mask and protect the surrounding surfaces, do the work and tidy away. Most jobs take a few hours, depending on how many layers have to come out. Parking around New Marston is usually easier than in a town centre, but mention any lanes, gates or long drives. For outside work, side access and the height of the joints help us plan.
- First we find out how and where the joint has failed.
- Every layer of old sealant is cut and cleaned out.
- We clean the joint, treat any mould and let it dry.
- Moving joints get backing and a flexible sealant to suit.
- The new joint is tooled neatly and we explain anything else we found.
Before we arrive
- Tell us about any water getting in
- For indoor joints, keep the area dry beforehand if you can
- Move anything stored near the joints
How to get a quote
Getting a quote is simple: let us know the job and the location and its rough size. Photos by email help us understand the job, and we will take it from there.

The quote reflects the job in front of us. We look at:
- Whether the work is at height

Instead of a standard rate, we look at what your job involves: the amount of work, the old material and the access. You’ll know the price before we begin.
Asking for a quote
You don’t need to know the technical terms. Just tell us:
- What’s wrong with the joints now
- The type of property
- The address or postcode of the job
- Whether it has been sealed before
For a quick quote, get us on the phone, or send an email if you’d rather. Tell us about the joints that need doing and we will talk you through the work before giving you a price.
Why deal with it now?
Mould under a bead can’t be reached by cleaning. Removal is the only way to get at it, and the joint treated and dried before resealing. In a smaller place like New Marston, 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.
Some things make a job bigger or smaller: how much old sealant there is and how stubborn it is, whether mould needs treating, and whether the work is at height. Your quote takes all of that into account.
What you get with us
- We leave the area clean and tidy
- Every job guaranteed for a year

DIY versus a professional finish
If you’re set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.
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.
For landlords and businesses
We also work for property managers and facilities teams. We can quote a run of properties together.
Whether it’s one flat or a portfolio, the work is the same standard: old sealant fully removed, joints prepared properly and a one-year guarantee.
Questions from New Marston
Do you work for hotels and guest houses in New Marston?
Yes, we work for hotels as well as homes and businesses. A room-by-room programme keeps most rooms in use while the work goes on.
Can you help a landlord with a rental near Oxford station?
Yes, landlords and agents are among the people we work for, and several properties can be quoted together. You can phone 0345 464 0079 or drop us an email with the details for a clear quote.
Are you ARBOMaster approved?
Yes. We are approved under the ARBOMaster scheme, the approved applicator scheme for Arbo sealants.
Can you fix a reseal that hasn’t worked?
Yes. Repeat leaks generally come from over-sealing, movement or water getting in elsewhere, so we find that first.
Do you take out the old sealant first?
Yes, always, and completely. New sealant will not bond properly to old, so the joint is cleaned back first.
Will it make a mess?
Very little: the area around the joints is protected first, and we clear up the old sealant and our materials before we leave.
Do the sealants smell?
It depends on the product. Some products have a noticeable smell, others very little, and any smell fades as they cure.
What happens if the problem is the tray or the plumbing?
You will hear it from us. A cracked tray, faulty valve or leaking waste needs a different trade, and we won’t reseal for the sake of it.
Remedial sealant in New Marston: local notes
New Marston has hotels and guest accommodation nearby. Hotel bathrooms are part of our work as well as homes, and can be done room by room. Most of the South East has hard water, which leaves limescale on sealant, grout and fittings.
Homes close to Saint Michael and All Angels include some older properties, and timber floors under older bathrooms flex, so joints need a sealant that moves with them. If you look after a building such as St Michael's CofE Primary School, washroom and kitchen sealant there needs the same care as at home, and schools and businesses are part of our work as well as homes.

Signs you need remedial sealant in New Marston
Products get mixed up: caulk where it gets wet, rigid sealant where things move, or an acetoxy silicone on a surface it can mark. Each fails in its own way.
These are the problems we’re asked about most:
- Caulk or the wrong sealant used in a wet area
- Beads that never stuck properly
- A shower that leaks however often it’s resealed
- Floor or wall movement joints that have failed
