Send drawings, photos or a joint schedule, or tell us about the site, and we’ll come back with a fixed quote.
Our process
Working in a building that stays open takes some planning. The work area is signed and kept contained, keep walkways clear and work section by section so the rest of the building stays in use. Planning a London job such as one in Brentford starts with access: booked loading, goods lifts, the building’s permit system and a spot to keep materials. Give us the hours we can be on site and we will schedule to suit.
- Every room is surveyed and the failed joints listed.
- You get a fixed quote with the phasing plan.
- The whole of the old bead is removed.
- Joints are degreased and dried.
- A sanitary silicone bead is laid and given a smooth tooled finish.
- Each area is handed back when ready.
Preparing the site
- Send your site hours and access windows
- Agree which areas must stay open
- Explain the parking and delivery arrangements

Advice
Washroom sealing in Brentford
Whether it’s a single toilet block in Brentford or a programme across several buildings, we work the same way: details first, then a fixed quote, then the work, then the 12-month guarantee. A few photos and a count of fittings are enough for a quick quote and a site visit is an option. If you have gaps where vanity tops meet the wall and shower tray joints that have opened up, we can help. One point of contact handles commercial sealant work in Brentford from the first photographs to the final walk-round, whether it’s one building or several.
Washrooms in London offices, hotels and gyms are used hard from morning to evening. Mouldy or split sealant at vanity tops, IPS panels and urinals is replaced with anti-mould sanitary silicone, in phases so some facilities stay open.
Our 12-month guarantee is about workmanship, not wear and tear. Sealant wears with time, and movement, weather, cleaning and use decide how fast, so we are clear about what is covered before work starts.

What affects the price in Brentford
What shapes the price:
- The product specified
- Site requirements such as inductions and permits
- The total length or number of joints
- How accessible the joints are
The product called for affects the cost, and so does the preparation, from cutting out to priming and backing rod. Access, phasing and site requirements come into it too.
Before you send an enquiry
It doesn’t need to be a full survey. A few details are enough to get going:
- When you need the work done
- Whether an asbestos survey exists
- Access details, including height
- Drawings or a marked-up plan, if available
Need a figure for a tender or a budget? Send the scope and any drawings, and we’ll return a fixed quote you can plan around. If you have questions first, speak to us on 01277 525 020 or send details through our quote form.
Aftercare for building managers
A few simple habits keep the new joints working:
- Brief cleaning staff to treat joints gently
- Act on the first split you see at a shower tray
- Share your site rules when you send details
- Clear standing water from shower floors where possible
Where possible, have shower floors and trays squeegeed after busy periods. Standing water on a joint all day shortens its life.
Leaks through tray and wet-floor joints can go unseen until a ceiling marks below. By then, other trades may be needed as well so failed joints are worth acting on quickly.
Washroom sealing in Brentford: the local picture
A 2-mile radius around Brentford takes in a good number of hotels. Behind every hotel door there’s a bathroom whose sealant will need renewing sooner or later. London offices and hotels typically can’t close all their washrooms at once, so we phase the work core by core or floor by floor with the building manager.
For a college such as Ealing and West London College, which lies north of Brentford, half-term and summer give the windows for washroom work. Customer toilets in retail centres such as Kew Retail Park (to the south-east of Brentford) rarely close, so resealing is phased.
Brentford is about 2 miles south of Ealing, in Greater London. Our applicators travel to Brentford for work on washrooms and wet areas. We work across 764 places in Greater London. Our London page has more on work in that area (9 miles or so).

Other services in Brentford
Site staff or a sealant specialist?
For most general trades, sealant is a sideline. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint, which is what makes a joint last.
Certain joints really need a specialist: for instance fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. Getting these wrong normally costs more in the end than doing them right.
FAQs: Brentford
Can you work in a London building with booked loading and goods-lift slots?
Yes. Booked loading bays, goods lifts and permit-to-work systems are normal for London jobs. Send the building rules and access times with your enquiry.
Must a hotel around Brentford close while you work?
In most cases no closure is needed: we work room by room or floor by floor. Housekeeping and our team agree each day’s rooms.
Are you fully insured?
Yes. Mastic Doctor is fully insured, public liability included.
Do you do washroom sealing in healthcare settings?
We work in clinics, hospitals and care homes. Any records you need are confirmed with the quote.
Is there a guarantee on the work?
A 12-month guarantee covers the work. It covers our workmanship rather than damage, leaks from plumbing or ventilation problems.
Will you quote for a small job?
Single areas, one-off repairs and whole buildings are all quoted the same way: details, then a fixed price, then sealing, then a 12-month guarantee.
What will the job cost?
Each job is quoted on its own details. To get one, speak to us on 01277 525 020 or email a schedule or drawings with a description of the work.
Signs you need washroom sealing in Brentford
Occasionally a joint keeps failing because of a problem behind it: loose fixings, a dripping trap or damp in the wall. We check for that first and tell you if another trade is needed.
Typical triggers for a call:
- Urinal joints that look unhygienic
- Failed joints along IPS and cubicle panels
- Sealant stained black around basins and showers
- Complaints from staff, guests or users about tired washrooms
For a site such as Clayponds Hospital, 0.5 miles to the north-east of Brentford, sanitary joints in clinical areas need sound, cleanable sealant and a careful method.

- Whether primer will be used where the manufacturer specifies it
