About our mastic sealing in Upper Norwood
Older blocks and commercial buildings can have mastic that contains asbestos. Before we disturb it, we ask to see the asbestos register or survey, and work stops for testing if there’s any doubt. Removing asbestos-containing material isn’t something we do. If you have leaks at window and door perimeters and draughts at frames across a block, we can put it right. Most enquiries from Upper Norwood start with one failed joint and grow into a wider look at the building: we check the joints around it and give you an honest view of what needs doing now and what can wait.
Across Greater London, Upper Norwood included, the ULEZ applies, and parking and loading rules differ from street to street. For block-wide work, a place to park and store materials saves time on every visit.
Every job is signed off with a 12-month guarantee. It’s a plain promise: if our work fails within that year, we put it right.

When something else is needed
We check first that sealant really is the fix. It won’t put right:
- Leaks through the frame itself rather than the perimeter
- Water coming in from the roof or rainwater goods
- Glazing that needs replacing
If in doubt, call 01277 525 020 or send details through our quote form and we’ll say what we think before you book.

Cost factors for mastic joints
Your fixed quote is built from the real scope. It allows for:
- Which sealant the job calls for
- Phasing around occupants
- Any access equipment needed
- Location, for remote and island sites
Small jobs and large programmes are priced from the same things: what’s in scope, how we reach it, what’s specified and when it needs doing. Call for a quote and we will put a fixed figure on it.
Before you send an enquiry
Diagnosis starts before we arrive. Tell us:
- Anything awkward about access or site hours
- The postcode of the building
- Whether the building will be occupied during the work
- Clear photos of the problem areas
Specifications, drawings and tender packages are welcome with any enquiry, and we’ll price against exactly what is specified. Smaller jobs need nothing more than photos and a few notes.
When to call us in Upper Norwood
Topping up old mastic is a common shortcut. New silicone has nothing to grip on old silicone, so these repairs rarely last.
Clients typically get in touch after noticing one or more of the following:
- A mix of products and colours from past repairs
- Complaints coming in block by block
- Window mastic that has split and shrunk
- Failed external movement joints
If you manage student housing near a university such as King's College London (3.4 miles north of Upper Norwood), the summer turnaround is the time for mastic.
What your quote should include
- Proof of insurance
- Will failed sealant be removed rather than covered?
- Their plan for phasing and protecting the area
- Which product they’ll use, and why it suits the joint

Advice
Why it’s worth doing now in Upper Norwood
Resealing ahead of leaks keeps it to a maintenance task. Once water has tracked in, the repair list grows, and the complaints come with it. Getting scaffold, permits or access booked in Upper Norwood takes effort, so while access is arranged it pays to renew all failing joints, not just the worst.
No two sites price the same: joint size, product, access and site hours all play a part. A fixed quote follows once we understand the job.
What you get with us
- Failed material removed, not covered up
- Fully insured, including public liability cover
- Colours confirmed for the specified product
- 12 months’ guarantee on every job

Common questions from Upper Norwood clients
Is Hamilton Road Industrial Estate, near Upper Norwood, within your area?
Yes. Our area takes in Upper Norwood and its surroundings, with estates and business parks such as Hamilton Road Industrial Estate included. A few photos and the unit address let us price the work.
Do you work for managing agents with blocks near Gipsy Hill station?
Yes, we work for agents, landlords and housing associations with blocks of every size. Give us the building’s details and say how residents are notified, and we’ll quote and plan to suit.
When can the area be used after sealing?
We will confirm how long the chosen product needs to cure, and sign any area that should be left alone.
Can you work to our specification?
Yes. Include it with the drawings when you ask for a quote, and the quote will be based on it, flagging anything that needs clarifying.
How long does a job like this take?
We plan the time on site around your programme and access. You will have an expected duration with the quote.
Does weather matter for sealant work?
It can, when the joints are outside. Wet joints and cold, damp or frosty conditions stop the sealant bonding properly, so we watch the forecast and rearrange outside work if we have to. Indoors, the weather is rarely a problem.
Can you take on resealing for a block portfolio?
We do. Managing agents, property factors in Scotland, housing associations and landlords with block or commercial portfolios are our main clients for this work and work can be quoted per building or as a whole.
Maintenance after handover
Keep the joints in good shape with a few simple steps:
- Mention RAMS, insurance or CSCS requirements up front
- Log resealing dates block by block
- Check sealant joints during planned building inspections
- Keep bins and bikes away from communal door frames
If paintable sealant was used, decoration can follow once it has cured. Non-paintable silicone shouldn’t be painted over.
Mastic fails gradually, then all at once in a wet spell. Acting at the first signs keeps it a straightforward reseal and the complaints that come with it.
