The process
Most of a good job is in the preparation, so that is where we spend the time. Joints are cleaned back and dried before anything new goes in. In total, it normally takes anything from a few hours to several days, depending on the number of rooms. In a small place like Southend, access is normally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We start by looking at the rooms and agreeing what’s needed.
- Working hours are agreed, including early starts or out-of-hours work where it can be arranged.
- Each area is protected and stripped of old sealant.
- Joints are dried, then resealed and tooled neatly.
- We let your team know the cure time for every area.
Getting ready for the visit
- Keep pets and children clear of the area while we work
- Clear the area around the work
- Let us know about stairs, lifts or work at height

Why deal with it now?
A leaking shower in a hotel room or flat above can damage the ceiling below. That means a second room out of use and a repair to pay for. Resealing first is the smaller job. Around Southend, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
Rather than a set price list, we look at what your job involves: how many joints, what’s in them now and how we reach them. You will know the price before we begin.

Common problems we fix in Southend
In office kitchens and tea points, joints are wet and wiped all day, so sealant there wears and stains. Worktop and sink joints are often the first to go.
These are the problems we are asked about most:
- Shower leaks reaching the floor below
- Split sealant around staff kitchen worktops and sinks
- Split sealant where wet room floors meet walls
- Large numbers of bathrooms needing the same work
If you let a flat or house near Portchester station, several rental properties can be resealed on one programme.

Surface by surface
Office washrooms & kitchens
A row of basins on a vanity top has a long joint that collects water. We renew it in one tidy, continuous bead.
Rental portfolios
Good sealant prevents leaks that cause bigger repairs.
How we quote for commercial sealant
Every job gets its own quote. These are the things that affect it:
- The product the joint needs
- Access and height
- The amount of work
- Mould in or behind the old joints
We do not show prices on the website, because each job is priced on what it involves. Call for a quick quote and we will talk you through it.
Asking for a quote
There’s no need for technical detail. Just tell us:
- Any access issues, like height or stairs
- A few photos by email, if you can
- What the problem is, such as mould, gaps, leaks or cracking
- Where the property is
It all starts with a short chat. Tell us what’s wrong, where it is and how much there is, and we’ll explain how we’d tackle it. Whenever you’re ready, phone 0345 464 0079 or send us an email.
When it isn’t the sealant
New sealant cannot fix everything, and we’d rather say so up front. Sealant will not put right:
- Failed tanking or loose tiles behind the sealant
- Leaking pipework, valves or wastes (a plumber’s job)
- Extraction that isn’t working, which needs an electrician or ventilation contractor
If in doubt, call 0345 464 0079 or email us and we’ll say what we think before you book.
What we seal
- Retail & leisure sites
- Hotel bathrooms
- Student & care accommodation
- Rental portfolios
- Welfare facilities

DIY versus a professional finish
If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it doesn’t work out, we can still put it right.
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.

Commercial buildings in Southend
Hard water is the norm across most of the South East, which leaves limescale on sealant, grout and fittings, and it has to be cleaned off before new sealant goes in.
Managing a site like Newtown Soberton Infant School? Then busy washrooms and kitchens can be resealed in phases so they stay open. If you look after a church, hall or community building such as Church of the Holy Trinity, halls and community kitchens see heavy use, and their sealant shows it.
