What the job involves on each surface
Office washrooms & kitchens
Long vanity tops have joints that hold water and grime. It’s cut out, cleaned and resealed in one neat line.
Welfare facilities
Shower rooms in welfare blocks get heavy use and need sound joints. Anti-fungal sanitary silicone is used throughout, accessible showers included.
What sealant work cannot fix
A few problems are outside what sealant work can do:
- A broken extractor fan behind the mould problem
- Cracked trays or baths rather than failed joints
- Water coming from plumbing rather than sealant

How the visit works
Good joint work is mostly preparation, so that is where we spend the time. Every joint is cleaned and dried before new material 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 Colwell, access is usually the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- We start by looking at the rooms and agreeing what’s needed.
- We agree when we’ll work, with early or out-of-hours slots where they can be arranged.
- Areas are protected and the failed sealant removed.
- Joints are dried, then resealed and tooled neatly.
- We let your team know the cure time for every area.
How to prepare
- Move anything stored near the joints
- Try not to wet indoor joints just before the visit
- Let us know about stairs, lifts or work at height

What affects the quote in Colwell
Your quote is based on your job. We take into account:
- How many areas need sealing
- Access and height
- The size of the job
- When we can work, for business premises
Combining jobs into one visit is usually more efficient than separate visits. You’ll get one clear quote for the whole job.
Asking for a quote
To make quoting easier, let us know:
- Whether it’s a home or a business
- Pictures of the joints, sent by email
- How we’d reach the joints
- What the problem is, such as mould, gaps, leaks or cracking
A good description makes for an accurate quote. Let us know the location, the problem and roughly how many joints.
Why deal with it now?
A quick bead over the old sealant might get a room back in use today, but silicone does not bond to silicone, so it lifts. Doing it properly once is less disruptive than doing it badly twice. In a small place like Colwell, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
Some things make a job bigger or smaller: the old material and how easily it comes out, whether mould needs treating, and whether the work is at height. We take all of that into account in your quote.

Workplaces and buildings in Colwell
For seaside hotels, guest houses and holiday lets around Colwell, heavy use in the busy months is hard on washroom and kitchen sealant, and any building work there should leave fire-rated joints made good. Most of the South East has hard water, so limescale builds up on sealant, grout and fittings.
If you look after a church, hall or community building such as Christ Church, halls and community kitchens see heavy use, and their sealant shows it. Letting a property close to Lymington Pier station? Then several rental properties can be resealed on one programme. Managing a site like All Saints Church of England Primary School? Then busy washrooms and kitchens can be resealed in phases so they stay open.

Looking after it afterwards
Aftercare is simple:
- Keep strong chemicals and scourers off the joints
- Check extract fans are actually running
- Add sealant to your planned maintenance checks
- Get split or lifting joints looked at early
Ask staff to report splits or lifting sealant early. A small gap caught quickly is a short fix.
Watch for the warning signs: mould, splits, peeling corners or water marks downstairs. When you see them, it’s time to plan a reseal.
Common questions in Colwell
Can you help a landlord with a rental near Lymington Pier station?
Yes, we work for letting agents and landlords. You can ring 0345 464 0079 or email us with the address and a few details, and we’ll give you a fixed price before work begins.
Will you come out to Colwell?
Yes, Colwell is covered. Our work covers London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.
Does commercial work come with a guarantee?
Yes, with our 12-month guarantee. Regular gentle cleaning and working extraction help the sealant last.
What do you need from me for a quote?
Only a few details: the address or postcode, what’s wrong and any access issues. Then call 0345 464 0079 or drop us an email.
Do you take out the old sealant first?
Yes. Sealing over old sealant is the main reason resealing fails early, so we never do it.
Can you do several jobs on one visit?
Yes, and it often makes sense. Combining jobs makes good use of the visit.
Can you reseal hotel rooms while we stay open?
Yes. We work through rooms in batches, keeping most rooms available. Housekeeping are told when each room can be let again.
Do I have to be there?
It depends on the job. For work indoors, someone needs to let us in, and for outside work we’ll agree access with you when we book.
