Surface by surface
Student & care accommodation
In care settings, we agree the order and timings with staff, and staff are told when each bathroom can be used.
Office washrooms & kitchens
Staff toilets, washrooms and kitchens get constant use, so we can work early or out of hours where that can be arranged. We reseal around basins, urinals, worktops and sinks.
When to call us in Northwood
Quick fixes come back quickly. New silicone over old, joints that weren’t dried, or an unsuitable product all lead to the same thing: another reseal before long.
Look out for these signs:
- Mouldy washroom sealant that staff and guests notice
- Too many rooms to reseal without closing the building
- Worktop sealant that has shrunk and stained
- Joints that need doing before an inspection or audit
Letting a property close to Carpenders Park station? Then sealant work can be quoted for a single flat or a whole portfolio.
What to look for in a quote
- Is VAT in the price?
- What preparation is included
- Which colour the sealant will be
- Which sealant they’ll use, and why
The process
At the end, we look at the finished work together and explain the cure time. The work normally takes a few hours per area, with larger sites planned over several visits, depending on how much there is to do. For a job in Northwood, parking and access are the things to plan: tell us about permits, visitor bays or off-street space, which floor we’re working on and whether there’s a lift.
- Tell us the rooms, hours and site rules, and we will 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.
- Each finished area is checked with you and given a cure time.
Preparing for the visit
- Mention if the joints have been sealed before
- For business premises, tell us about site rules or sign-in
- Clear items away from the joints we are working on

Your quote is based on your job. We look at:
- The size of the job
- Access and height
- How many rooms, windows or areas are involved
- Whether there’s mould to deal with
Leaving a failed joint usually makes the job bigger, not smaller, because water and mould keep working on it. If you’re not sure whether it needs doing, ring 0345 464 0079 or email us for an honest opinion and a quote.

- Where the job is, and your postcode
- A few pictures by email, if you can
- Access, such as stairs, a lift or height

What else we do in Northwood
Keeping the joints in good condition
So the new joints stay in good condition:
- Keep extractor fans working and serviced
- Leave squeegees in busy showers
- Check the joints during routine room inspections
- Book larger programmes for quieter times of year
Make it easy for staff to flag a failing joint. Catching one split early can save a leak later, and if anything looks wrong, just call 0345 464 0079 or send us an email.
Signs to look for: black spots in the silicone, corners lifting, staining on the ceiling below or a musty smell. When you see them, it’s time to plan a reseal.
Commercial sealant around Northwood
Many London buildings have tight access and loading restrictions, so out-of-hours working can be arranged where needed. London has hard water, which leaves limescale on sealant, grout and taps.
Northwood is in London, so parking needs planning: tell us about permits, visitor bays or off-street space when you book. For site and facilities teams at buildings such as Frithwood Primary School, busy washrooms and kitchens can be resealed in phases so they stay open.
Northwood is about 3 miles south-east of Rickmansworth, in Greater London. From the centre of Northwood to the outskirts, we cover commercial sealant for every kind of property, from flats and houses to offices and hotels.

Leave it or put it right?
Fixing rooms one complaint at a time is the slow way. A planned programme works through every room, with less disruption and one clear quote. In older London homes, water behind a failed joint soaks into brick and timber without much sign, and by the time it shows on a wall or ceiling in Northwood, the repair is bigger than the sealant job would have been.
Every job is a little different, so we quote each one individually. The number of joints, how easy they are to reach and the sealant needed all make a difference.
Why book with us
- Over 20 years’ experience
- Homes, businesses and hotels
- A 12-month guarantee on all work
- Sealant colour chosen to suit
DIY versus a professional finish
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.
Common questions in Northwood
Is parking an issue for commercial sealant in Northwood?
Parking in Northwood, as in most of London, takes a little planning: a visitor permit or a bay close to the door helps a lot, so mention what’s available when you book.
Is Northwood in your area for commercial sealant?
Yes, Northwood is within the area we cover. We work across London and the South East. You can call 0345 464 0079 or email us and tell us what needs doing, and we’ll send you a clear quote.
What do you put in the joint?
Each joint gets the product that suits it. Where it moves, gets wet or faces the weather makes a difference, and we will explain our choice.
Can you reseal every bathroom in a hotel?
Yes, we can. Larger jobs are planned as a room-by-room or floor-by-floor programme, so only part of the building is affected at once.
Can I do it myself?
Sometimes. The key is preparation: remove all the old material and work on a clean, dry joint. If it doesn’t work out, we can redo it.
Can you supply method statements and risk assessments?
We’re fully insured, and we’ll go through your site’s requirements with you. We’ll confirm what we can supply when we quote.
Are you an approved applicator?
Yes. ARBOMaster is the approved applicator scheme for Arbo sealants, and we are part of it.
How much does commercial sealant cost in Northwood?
There’s no set price, as it depends on the job: its size, the old material, access and the product needed. You’ll get a clear quote before work begins.
