Looking for mastic applicators who cover Kingsmead? Mastic Doctor has worked for contractors, FMs and building owners since 2005.
In and around smaller places like Kingsmead, washroom work is often in halls, pubs, primary schools, care homes and holiday accommodation. Sealant that has gone black with mould usually can’t be cleaned, so it is cut out and replaced.
Our workmanship is guaranteed for 12 months, in Kingsmead as everywhere else we work. If a joint we sealed fails because of how it was installed, we come back and put it right.

Washroom sealing in Kingsmead: the local picture
At about 61 miles from central London, Kingsmead is within reach of the capital, within the office belt around the capital. Office toilets in the commuter belt are in use from first arrivals to last departures, so we phase work to keep some facilities open. The area within 2 miles of Kingsmead holds a number of hotels. Each has en suites, back-of-house toilets and kitchens with sealant that moulds and splits. Rooms are done in turn so most stay available.
For buildings on a site such as Waltham Business Park, which lies north-west of Kingsmead, washrooms and tea points can be resealed in phases through the working week. Healthcare estates like Knowle Hospital, 3.1 miles to the south-west of Kingsmead, expect contractors to follow their permits and cleaning rules in every washroom. At a school such as Swanmore College of Technology, changing rooms and kitchens need cleanable joints as much as the toilets.
Kingsmead is about 5 miles north of Fareham, in Hampshire. We cover commercial sites throughout Kingsmead, whether it’s a single job or part of a planned programme. 723 places across Hampshire fall within our area, Kingsmead among them. For work in that direction, see our Portsmouth page (9 miles or so).

Diagnose, treat, sign off
At the end of each section, the masking comes off, the area is cleaned and every joint is checked. If an area should be left alone while the sealant cures, we say how long and put signs out. For work around Kingsmead, we aim to finish in one visit, so photos and measurements up front really help. Then the right materials arrive with us.
- We start by inspecting the fittings and joints and flagging problems sealant can’t solve.
- A phasing plan keeps part of the building’s facilities in use at all times.
- The failed silicone is stripped and every face scraped clean of residue.
- Joints are cleaned, degreased and dried before sealing.
- New sanitary silicone with anti-mould additives goes in and is tooled neat.
- You get a reopening time for every room, with signage left up until then.
Preparing the site
- Tell us which areas need to stay in use
- Make sure the joints can be reached
- Warn occupants and staff about the work

What sets the cost
Your fixed quote is built from the real scope. It allows for:
- Backing rod, priming and other preparation
- How much existing material needs removing
- How accessible the joints are
- Quantities, in metres or numbers
The price depends on how many linear metres there are, what has to come out first and how the joints are reached. Call for a quote once you have the details.
What we need to price the job
The more we know, the firmer the quote. Helpful details to send:
- Where the site is, with the postcode
- Any dates the work must fit around
- Drawings or a marked-up plan, if available
- Any specification or named product
The quickest route to a quote is a few photographs and the site postcode. Upload them with the quote form, or speak to us on 01277 525 020 or send details through our quote form if you’d rather talk the job through.
When it isn’t the sealant
Sealant solves a lot, but not everything, and we’d rather tell you before you spend money. It won’t fix:
- Failed tanking beneath a wet-room floor or behind tiles
- Panel boards already damaged by water
- Water from plumbing, not from a joint
If you’re not sure, just call 01277 525 020 or send photos by email and we’ll give you a straight answer.
What we seal
- Vanity units and basins
- Showers, trays and wet room floors
- IPS panels and cubicles
- Urinals and WCs
- Kitchens and tea points
- Accessible toilets and changing rooms
Questions we’re asked in Kingsmead
Will our hotel in Kingsmead need to close for the work?
Rarely, if ever. We take a few rooms out at a time. We agree the order of rooms and the timings with you before we start.
Is Kingsmead too far out for you?
Not at all: smaller places are covered as well as towns. Our area covers London and the South East counties. Where we can, we group nearby jobs to make the most of each trip.
How much does the work cost?
Each job is quoted on its own details. For yours, give us a call on 01277 525 020 or send details through our quote form.
Is any job too small?
We quote for single jobs as well as large packages and programmes. Send details for a fixed quote.
How long will the new sealant last?
There’s no fixed lifespan: movement, exposure, cleaning, traffic and the product all play a part. Treat them as maintenance items and inspect them regularly.
Can you reseal washrooms in healthcare buildings?
We do. We work to your estates and infection-control requirements and any site permits, and phase the work so areas keep facilities.
How long does a typical visit take?
It depends on the scope, though a typical visit usually takes a few hours for one toilet block, with bigger buildings phased across a number of visits. For bigger or phased jobs, we will set out a timescale with the quote.
How the job changes by surface
Wet-room floors and floor-to-wall joints
Wet-room floors and the joints where flooring turns up the wall need to stay sound. Floor perimeters and sealant joints near drains are resealed.
IPS and cubicle panels
Swollen or delaminated boards need replacing, and any we come across will be pointed out.
Maintenance after handover
To get the most from the new sealant:
- Clear standing water from shower floors where possible
- Mention any site permits or estates rules at quote stage
- Leave signs up until the cure time is over
- Keep extract fans working and vents clear
Any failure in our workmanship within the 12-month guarantee is ours to put right. After that, a routine look catches failing joints early.
Mould in a joint spreads along the bead and into nearby grout and users notice. Replacing it early keeps the job to a reseal.
When to bring in a specialist
For a quick touch-up, site staff may be fine, but anything bigger is another matter: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.
A short, simple internal joint is often within reach of a maintenance team. The usual problems come from preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.
