How we handle commercial sealant in Broad Colney
Office kitchens, staff washrooms and welfare facilities need to be usable every working day. We can plan the work for early mornings or out of hours so the working day is disturbed as little as possible. You are told when each area can be used again. We are often asked to deal with tired sealant in let properties and washrooms that need sorting before an inspection, across welfare facilities, rental portfolios and student & care accommodation.
Somewhere as small as Broad Colney, commercial jobs tend to be pubs, holiday lets, farm buildings or halls rather than offices. They all have washrooms, kitchens and service openings that need the right sealant.
You are covered for a year from the day we finish. If there’s a problem with it, please ring 0345 464 0079 or drop us an email.

When to call us in Broad Colney
Commercial bathrooms get far more use than domestic ones, and they’re cleaned with strong products every day. So the silicone ages faster than it would at home.
Any of these means the joints need attention:
- Water marks on ceilings under bathrooms
- Tired sealant in let properties
- Too many rooms to reseal without closing the building
- Washroom sealant that looks dirty however often it’s cleaned
If you let a flat or house near Park Street station, sealant work can be quoted for a single flat or a whole portfolio.

What else we do in Broad Colney
Commercial sealant around Broad Colney
Most of the South East has hard water, which leaves limescale on sealant, grout and fittings, and it has to be cleaned off before new sealant goes in.
Schools such as Saint Bernadette Catholic Primary School are buildings too, and sealant in washrooms, kitchens and changing areas can be renewed around term times or opening hours. If you look after a church, hall or community building such as Church of St Peter, any kitchen and washrooms need the same sealant care as any other building.

How the visit works
Good joint work is mostly preparation, and we do not rush it. Every joint is cleaned and dried before new material goes in. In total, it normally takes a few hours for a single washroom, longer for a whole building. In a small place like Broad Colney, access is generally 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.
- Areas are protected and the failed sealant removed.
- Once dry, every joint is resealed and tooled.
- Housekeeping or site staff are told when each area can be used.
How to prepare
- Tell us about any previous sealing or DIY attempts
- Keep children and pets away from the work area
- Mention any tricky access

How we quote for commercial sealant
For a quick quote, just ask. What matters most is:
- How easy the joints are to reach
- The number of rooms or windows
- When we can work, for business premises
- Which sealant suits the joint
A few things move the cost up or down: how much old sealant there is and how stubborn it is, any mould to treat, and whether the work is at height. Your quote takes all of that into account.
Helping us quote
To make quoting easier, let us know:
- If someone has resealed it before
- Where the property is
- Photos by email, if that’s easy
- Whether it’s a home or a business
We don’t publish a price list. Instead, we give you a clear quote for your job. To arrange one, phone 0345 464 0079 or email us.
How to look after the new joints
A little care helps the new joints last. We recommend:
- Schedule work around occupancy
- Check extract fans are actually running
- Use mild cleaners on sealant, not bleach or abrasives
- Leave squeegees in busy showers
A squeegee in each shower is a simple help: less water sits on the joints between uses.
Water from a failed shower seal can travel: through floors, into ceilings and across into corridors. Dealing with the joint early stops that spread.
Should I try it myself first?
Sealing over old silicone is the commonest DIY error. Silicone does not stick to old silicone, so it lifts and traps water and mould underneath. All the old material has to come out first.
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 does not work out, we can still put it right.

Why it’s worth doing now in Broad Colney
Patching the worst rooms as complaints come in is hard to manage. A planned programme works through every room, keeping disruption down and costs clear. In a small place like Broad Colney, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
Combining jobs into one visit is normally more efficient than separate visits, so it’s worth mentioning everything you’d like done. You’ll get one clear quote for the whole job.
