FAQs for Southrope
Do you work for landlords with property near Alton station?
Yes, we work for letting agents and landlords. Just ring 0345 464 0079 or email us and tell us about the property, and we will give you a clear quote.
Is Southrope within the area you cover?
Yes, smaller places are covered as well as towns. We work across London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Will you leave a mess?
No. We work neatly, protect the area around the joints and tidy up afterwards.
Where are you based?
We’re a Crawley-based firm, with over 20 years’ experience. Our area covers South East England, London and Scotland.
Can I choose the sealant colour?
Generally, yes. Sealants come in white, clear, grey and other colours for many products, and we will agree it with you first.
What do you put in the joint?
We choose the sealant for the joint, not the other way round. Movement, water and weather all affect the choice, and we’ll tell you what we’re using.
Can I do it myself?
For a simple, easy-to-reach joint, a careful DIYer can do a reasonable job. Most DIY failures come from sealing over old material, wet joints or too much sealant.
Is it OK to seal over old sealant?
No. Fresh sealant does not stick to old sealant, and it traps any mould or water underneath. It all has to come out first.
Commercial sealant for homes and businesses in Southrope
Wet areas get anti-fungal sanitary silicone, and kitchens get a food-safe product where it’s needed. We use sealants from Arbo and Everbuild, applied by ARBOMaster approved applicators. If you have large numbers of bathrooms needing the same work and leaks from showers into rooms or ceilings below, we can help, whatever the surface.
For holiday lets, converted business premises or a community building near Southrope, washroom and kitchen sealant and any fire-rated joints need the same attention as anywhere.

How we quote for commercial sealant
We don’t publish a price list. The quote depends on:
- Whether old sealant or filler has to be cut out
- The type of sealant required
- Working hours on commercial sites
- Whether the work is at height
What it costs depends on the size of the job, how hard the old material is to remove and access to the work. You will have a clear quote before any work starts, so you know where you stand.
Asking for a quote
Photos help, but a description is a good start. Try to tell us:
- If someone has resealed it before
- What the problem is, such as mould, gaps, leaks or cracking
- Where the job is, and your postcode
- Roughly how big the job is
For a quote, ring 0345 464 0079 or drop us an email and tell us where the job is and what the problem looks like. We will send you a clear quote before any work starts.
What happens if it’s left?
Guests and staff judge a building by its bathrooms. Black sealant makes a clean room look dirty, and scrubbing won’t fix it. New sealant does. Around Southrope, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
The cost reflects the work involved, not guesswork. That’s why we ask about the job first and agree the price before starting.

Keeping the joints in good condition
Joint life depends on how it’s used and looked after. Here’s what we suggest:
- Get split or lifting joints looked at early
- Give housekeeping the cure time for every room
- Encourage users to squeegee shower walls
- Plan resealing around quiet periods
Ask staff to report splits or lifting sealant early. Catching one split early can save a leak later.
Black sealant in a staff washroom or guest bathroom draws complaints. Left long enough, it spreads through the bead, so the fix is replacement.
What we cannot put right
New sealant can’t fix everything, and we will tell you before we start. Sealant will not put right:
- Assessing what fire stopping a building needs
- Cracked trays or baths rather than failed joints
- Poor ventilation that keeps bringing mould back
Not sure which it is? You can phone 0345 464 0079 or drop us an email and we will tell you honestly.
Surfaces we seal

- Welfare facilities
- Rental portfolios
- Office washrooms & kitchens

How it works
When we arrive, we start by going over the job with you, so there are no surprises. We protect the surfaces around the joints before we start. Most jobs take a morning for a small washroom, and a planned programme for bigger sites. In a small place like Southrope, access is generally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- Tell us the rooms, hours and site rules, and we’ll plan the programme.
- We go through your site’s paperwork needs, such as RAMS, before work begins.
- In each room, the old bead comes out and the joint is cleaned and treated.
- We reseal with the right product for each joint.
- Rooms are handed back in order, each with its cure time.
How to prepare
- Keep pets and children clear of the area while we work
- Clear items away from the joints we’re working on
- Tell us about access, such as stairs, a lift or high-level joints
Getting a quote

Related advice
Do you need commercial sealant in Southrope?
Plenty of commercial bathrooms have no window at all, so if the fan is weak, steam lingers and the sealant stays damp. Mould then takes hold in the silicone.
Common reasons people contact us include:
- Silicone laid over old silicone by a previous contractor
- Tired sealant ahead of a health and safety audit
- Tired sealant in let properties
- Washroom sealant that looks dirty however often it’s cleaned
For landlords with property near Alton station, sealant work can be quoted for a single flat or a whole portfolio.
Before booking anyone
- What happens if they find a problem under the old sealant
- Whether they’re fully insured
- How long the guarantee is
- Whether the sealant suits the joint
