Commercial mastic work in Upper Norwood
Commercial occupiers rarely want a floor out of action for sealant work. Work is scheduled around the site hours and access windows you give us. That applies whether the building is an office, a shop, a hotel, a college or a care home. We work on washrooms and tea points, movement joints in walls and floors and floor and threshold joints, and the failures we’re asked to look at most are leaks that seem to come through a sealant line and black mould through washroom sealant that won’t clean off. For commercial sealant work in Upper Norwood, you deal with one contact from quote to sign-off, whether it’s one building or several.
The most common commercial job in Upper Norwood is resealing joints that have simply reached the end of their life: hardened, cracked or shrunk away from the faces, and letting water or dirt in.
London’s commercial stock mixes period buildings turned into offices with modern glass and steel, which means one visit can cover joints against stone, brickwork, coated aluminium and shop-fit panels. The right product goes on each, in a colour chosen to suit where the joint is seen.
Every job we finish is backed by a 12-month workmanship guarantee, in Upper Norwood as everywhere else we work. If a joint we sealed fails because of how it was installed, we come back and put it right.

Commercial sealant contractors in Upper Norwood: the local picture
Five care or nursing homes sit less than 2 miles from Upper Norwood. Kitchens and communal rooms in care settings are cleaned constantly, so their joints need to be smooth and sound. A 2-mile radius around Upper Norwood takes in a number of hotels. In hotels, sealant shows everywhere, from bathroom joints to reception counters, so colour and a clean finish matter, with rooms done in turn while the rest stay let.
A hotel such as Astra Palace Hotel (to the north-east of Upper Norwood) shows how much sealant a hospitality building has on show, from bathroom joints to the bar. If you run a unit on an estate such as Hamilton Road Industrial Estate, 0.6 miles north of Upper Norwood, the trade counter, offices and staff facilities have joints to look after as well as the warehouse.

Questions about Upper Norwood
Do you work in London buildings with loading restrictions?
Yes. Inductions, permits and timed loading are routine for us in London. Say when the building is occupied and when it’s quiet, and we’ll plan accordingly.
Must a hotel around Upper Norwood close while you work?
Rarely. Rooms or floors are done in turn, so the rest of the hotel keeps trading. We agree the order of rooms and the timings with you before we start.
Does commercial sealant work come with a guarantee?
Our workmanship is guaranteed for 12 months. Public liability insurance is in place too.
Can you follow the specification on our project?
Yes. Include it with the drawings when you ask for a quote, and the quote will be based on it.
Are you CHAS accredited?
Yes. We are CHAS accredited, we are a Constructionline member and we use CSCS-carded applicators.
Will you just go over the old sealant?
No. We cut the old material out and clean the joint back before sealing, since fresh sealant will not bond reliably to aged material.
What about asbestos in old mastic?
On older buildings, our first request is the asbestos survey. Managing asbestos is the dutyholder’s responsibility and removing it isn’t something we do.

Our process
We bring the products specified for the job, along with primers and backing rod. Joint faces are cleaned back to sound, dry surfaces, primer goes on where the manufacturer specifies it, and the sealant is tooled off neatly. The ULEZ covers the whole of Greater London, and parking near a job is rarely simple. Let us know about any on-site parking or loading arrangements when you send the job details.
- Site photographs, drawings or a visit tell us what’s there and how it has failed.
- You get a fixed quote covering removal, preparation and the new sealant.
- Sequence, access and working times are settled before the first joint is touched.
- The failed sealant comes out and the faces are prepared, with primer where required.
- Backing goes in, the new sealant is laid and tooled, and the area is left neat.
- We hand back each area with its cure time and our 12-month guarantee.
Preparing the site
- Confirm the product named in the specification
- Warn occupants and staff about the work
- Send your site hours and access windows

Related advice
Do you need commercial sealant contractors in Upper Norwood?
Washrooms and kitchens wear sealant out in their own way. Damp, harsh cleaning products and poor ventilation let mould take hold inside the bead, and once established it rarely cleans out. Replacement with a sanitary anti-mould silicone is the lasting answer.
It’s worth sending us details if you spot any of the following:
- Mouldy silicone around WCs, urinals and vanity tops
- Damp patches where an external joint has failed
- Greasy, split joints in a kitchen or tea point
- Movement joints packed with grit and debris
Shops and cafés around stations like Gipsy Hill station, less than half a mile to the north-east of Upper Norwood, trade from early, so work is timed around them.

- How joint depth will be controlled
- Will CSCS-carded applicators be on site?

Cost factors for sealant joints
Before we quote, we look at:
- Working within restricted access windows
- The size and state of each joint
- The total length or number of joints
- Whether old sealant has to be cut out first
The product called for affects the cost, as does the preparation each joint needs, such as cutting out, priming or new backing rod. Access, phasing and site requirements come into it too.
Before you send an enquiry
For an accurate fixed quote, we need to understand the site. Useful things to include:
- What the building is and how it’s used
- The postcode of the building
- Photos of the joints, close up and from further back
- Any specification or named product
Quotes are fixed against the scope you send, so the cost is agreed before work starts. To start the process, speak to us on 01277 525 020 or email a schedule or drawings.
Honest limits
Our job is the joint, not everything around it. Sealant alone won’t deal with:
- Walls or slabs moving more than any sealant can take
- Broken glass or blown double-glazed units
- Removing asbestos-containing materials (a licensed or specialist contractor’s job)
If in doubt, give us a call on 01277 525 020 or use the quote form and we will say what we think.
Where we work in Upper Norwood
- Movement joints in walls and floors
- External facade joints
- Washrooms and tea points
- Window and door perimeters
- Kitchen worktops and splashbacks
- Floor and threshold joints
Different surfaces, different methods
Window and door perimeters
Inside, cracked sealant around frames and window boards is common. We use a paintable product where decorating follows and a silicone where it doesn’t, matched to the frame colour where colour matters.
Fire-rated seals where specified
Where the specification calls for fire-rated or intumescent sealant around service penetrations or linear gaps, we install it to the product’s tested detail. The design and sign-off of fire stopping belong to the designer and building control, and we install to the specification.
Doing it in-house
Certain joints really need a specialist: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. Getting these wrong normally costs more in the end than doing them right.
For a quick touch-up, site staff may be fine, but larger jobs are different: a specialist brings efficiency, a consistent finish and a 12-month guarantee.
