About our washroom sealing in Middlegreen
In a busy washroom, the sealant typically gives up long before the tiles or fittings. Around basins, urinals, cubicles, IPS panels and shower trays it takes water, soap, cleaning chemicals and knocks every day and mould that roots into it can’t be cleaned away. We strip it out and lay new anti-mould sanitary silicone. If you have a new bead over an old one coming away and black mould inside silicone joints that cleaning can’t shift, we can put it right. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, in Middlegreen it comes down to the same thing: the right product in a properly prepared joint.
Halls and community buildings near places like Middlegreen are used by different groups through the week, and their toilets and kitchens show it. Resealing sinks, worktops and WCs with anti-mould silicone keeps them clean and watertight.
The 12-month guarantee covers our workmanship: preparation, application and finish. It doesn’t extend to damage, other trades’ later work or movement the joint was never designed to take.

Why it’s worth doing now in Middlegreen
Leaving the job until a shutdown often means living with it for months. With phasing, the work can go ahead while most facilities stay open. Around Middlegreen, it’s better to renew all the failing joints at once, rather than one at a time. Photos of every joint help us quote for the whole job.
The work involved drives the cost: stripping out, preparation, sealing, access and phasing. Call for a fixed quote and we will explain how it’s made up.

Then we strip out anything that has failed, prepare every joint and seal it.

What affects the price in Middlegreen
These are the things that shape the price:
- How accessible the joints are
- Distance, for remote addresses
- The product specified
- The total length or number of joints
Every site prices differently: joint size, product, access and site hours all play a part. A fixed quote follows once we understand the job.
Before you send an enquiry
Diagnosis starts before we arrive. Tell us:
- Drawings or a marked-up plan, if available
- Clear photos of the problem areas
- The product your specification calls for
- The asbestos register, for older buildings
Specifications, drawings and tender packages are welcome with any enquiry, and we will price against exactly what is specified. Smaller jobs need nothing more than photos and a few notes.
Should maintenance staff do it?
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.
A short, simple internal joint is often within reach of a maintenance team. Where it goes wrong is preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.
Your questions answered
Will you plan work around the academic year at somewhere like Brunel University of London?
Yes. We plan campus work around teaching, exams and residence turnarounds. Tell us which site documents you need, such as RAMS, our insurance certificate or CSCS details, and they’re confirmed with the quote.
Is a smaller place like Middlegreen outside your area?
Not at all: smaller places are covered as well as towns. London and every South East county are within our area. Send photographs and a list of what needs doing, and we will plan the job to need as few trips as possible.
How do you deal with asbestos in old sealant?
The duty to manage asbestos sits with the building’s dutyholder, so we’ll ask for the register before work on an older building. Work pauses if suspect material is found, until it has been tested.
How do we ask for a quote?
There are four steps: send details, get a quote, we seal, guaranteed. The first step only needs photos and a postcode.
Are you fully insured?
Yes. Mastic Doctor is fully insured, public liability included.
Can you clean the mould off instead of resealing?
Usually not. The mould is inside the silicone so cleaning only lightens it for a while. Replacing the bead is the lasting answer.
Do you hold CHAS accreditation?
Yes. We are CHAS accredited and a Constructionline member, which helps with supplier vetting.

- Sealant laid over old silicone and now peeling
- Open joints at the base of cubicle panels
