Workplaces and buildings in Penton Grafton
Most of the South East has hard water, which leaves limescale on sealant, grout and fittings.
If you look after a building such as Harrow Way Community School, busy washrooms and kitchens can be resealed in phases so they stay open. For buildings such as Holy Trinity Church, halls and community kitchens see heavy use, and their sealant shows it.

What happens if it’s left?
Fixing rooms one complaint at a time is the slow way. A planned programme deals with every room in order, with less disruption and one clear quote. Older cottages and farmhouses around Penton Grafton can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
The cost reflects the work involved, not guesswork. That is why we ask about the job first.
Why us?
- Sealant colour chosen to suit
- Approved under the ARBOMaster scheme
- We agree the colour with you first
- 20+ years of sealant experience
Should I try it myself first?
A DIY attempt doesn’t rule out a professional job. We remove it and do the joint properly.
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.
Looking after it afterwards
Looking after new joints is easy:
- Don’t leave a failed joint until the next refurbishment
- Encourage users to squeegee shower walls
- Schedule work around occupancy
- Tell cleaning staff when each room can be used
Add sealant checks to your planned maintenance. Checking joints alongside other room checks catches failures before they leak.
Watch for the warning signs: black spots in the silicone, corners lifting, staining on the ceiling below or a musty smell. Any of these means the joints need attention.
Signs you need commercial sealant in Penton Grafton
Staff kitchens and food areas see constant splashing and wiping, and grease and cleaning sprays break down sealant. Worktop and sink joints are often the first to go.
People usually contact us when they notice something like this:
- Mouldy bathrooms flagged at a tenancy check
- Shower leaks reaching the floor below
- Split sealant around staff kitchen worktops and sinks
- Large numbers of bathrooms needing the same work
For landlords with property near Andover station, we can quote for one property or a whole portfolio of rentals.
What to look for in a quote
- Who does the work, and how experienced they are
- Whether the sealant suits the joint
- How the colour is chosen
- How the surfaces are prepared before sealing
Penton Grafton: your questions answered
Do you work for landlords with property near Andover station?
Yes, we work for landlords and agents. You can phone 0345 464 0079 or send us an email with the address and a few details, and we’ll give you a fixed price before we start.
Will you come out to Penton Grafton?
Yes, Penton Grafton is covered. 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.
How soon can a room be used after resealing?
Around 24 hours is typical for sanitary silicone. We tell your team the cure time for every area.
Do you take on large, multi-room jobs?
Yes. With more than 20 years’ experience and over 2,847 projects behind us, we plan big jobs so the building keeps running.
Where is Mr Mastic based?
Our base is Crawley, with over 20 years’ experience. We work across South East England, London and Scotland.
Can you send RAMS and insurance details for our site?
Let us know which documents your site needs, for example RAMS or insurance details, and we will confirm what we can provide when we quote.
How long will you be here?
Most jobs take a morning for a small washroom, and a planned programme for bigger sites. We will confirm how long when we quote.
Do you guarantee commercial jobs?
Yes. Our one-year guarantee covers commercial work too.
When something else is needed
We’d rather tell you now than do work that will not last, so here’s what sealant can’t put right:
- Fire risk assessments or certification
- Water coming from plumbing rather than sealant
- Extraction that is not working, which needs an electrician or ventilation contractor
Not sure which it is? You can phone 0345 464 0079 or email us and we will tell you honestly before booking.

How it works
We bring everything the job needs with us. Once we have agreed what’s being done, we protect the area and start. Most jobs take a few hours for a single washroom, longer for a whole building. For a village or hamlet like Penton Grafton, 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 agree a programme with you: which rooms, in what order, at what times.
- We go through your site’s paperwork needs, such as RAMS, before work begins.
- In each room, the old bead comes out and the joint is cleaned and treated.
- We reseal with the right product for each joint.
- Each finished area is checked with you and given a cure time.
Preparing for the visit
- Clear the area around the work
- Let us know about stairs, lifts or work at height
- Keep children and pets away from the work area
