Expansion joint sealing in Upper Norwood
Mastic Doctor has sealed movement joints since 2005 for contractors, facilities managers and owners. CHAS accredited, Constructionline member, CSCS-carded applicators and five million pounds of public liability insurance. Each job is backed by a 12-month guarantee on the workmanship. We work on brickwork movement joints, precast concrete panel joints and car park decks and ramps, and the usual reasons a site gets in touch are movement joints with split or torn sealant and expansion joints filled with dirt and stones. A single leaking joint is often how a building in Upper Norwood first comes to us: we check the joints around it and give you an honest view of what needs doing now and what can wait.
Areas such as a loading bay or car park deck in Upper Norwood usually have to stay in use. We work through joints a section at a time, closing small areas in turn, at times agreed with the building manager.
Our 12-month guarantee is about workmanship, not wear and tear. How long a sealant joint lasts depends on movement, exposure, cleaning and use, so we spell out the cover before we begin.

Doing it in-house
Using site staff can make sense for a small touch-up, but larger jobs are different: a specialist brings efficiency, a consistent finish and a 12-month guarantee.
Some joints are best left to specialists: for example fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. Getting these wrong normally costs more in the end than doing them right.
FAQs: Upper Norwood
Is a hospital such as British Home & Hospital for Incurables somewhere you can work?
Yes, provided the work is planned with the site’s estates team. We follow the site’s permits, sign-in and infection-control procedures in every area.
Do you work in London buildings with loading restrictions?
Yes, most London buildings have access rules of some kind, and we plan around them. Send the building rules and access times with your enquiry.
Do you need to see the site first?
Photos, drawings or a schedule are often enough to quote. If the job needs a look first, we will arrange a visit before quoting.
When can you be on site?
Mention the site’s hours and access windows in your enquiry, and we will schedule the work to suit. You can reach the office between 8am and 5pm, Monday to Friday.
What about RAMS and site documents?
Requirements differ from site to site, so list what you need, whether RAMS, insurance or CSCS details, and we will confirm with the quote.
How much does the work cost?
That depends on the job: the volume of work, the access, the specified product and how it’s phased. Call for a quote.
Do you use silicone or polyurethane in movement joints?
The right product depends on the joint. Low-modulus neutral-cure silicone suits many facade joints, while polyurethane is common in trafficked floor and deck joints.
How the quote is worked out
Quotes vary with the job. Expect it to depend on:
- How accessible the joints are
- Whether old sealant has to be cut out first
- Location, for remote and island sites
- Induction, permit and paperwork requirements
The specified product makes a difference, and so does the preparation, from cutting out to priming and backing rod. Access, phasing and site rules also count.
Sending details for a quote
A good diagnosis starts with the right details. Let us know:
- Any dates the work must fit around
- Anything awkward about access or site hours
- Clear photos of the problem areas
- The site address and postcode
Photos, drawings or a schedule of the joints and a fixed quote comes back to you. If the job needs a look first, we’ll arrange a site visit.
How a job runs
In a busy building, the work is phased so only one area is out of use at a time. Each section is protected, cleaned back and sealed, then reopened once the sealant allows before the next one starts. Planning a London job such as one in Upper Norwood starts with access. Give us the hours we can be on site and we’ll schedule to suit.
- The first job is to check each joint: how wide it is, how it moves and why the old seal let go.
- A fixed quote follows, naming the sealant and its movement class.
- Old sealant and filler are cut out and the joint faces cleaned back to sound material, and we tell you if any edges need repairing first.
- We control the depth with backing rod or, in shallow joints, bond-breaker tape.
- Primer goes on where the manufacturer specifies it, followed by the sealant, which is then tooled off.
- Finished joints are checked and backed by our 12-month guarantee.
Getting the site ready
- Explain the parking and delivery arrangements
- Make sure the joints can be reached
- Point out any areas we must not close

Joints that move: notes for Upper Norwood
Few London car parks or loading bays can be taken out of use for more than a short spell, so we seal in sections and hand areas back as each cures. Upper Norwood has at least three named business or industrial parks inside a 3-mile radius. That puts plenty of warehouse floors, service yards and car parks close by, all with joints under traffic.
For an estate such as British Home & Hospital for Incurables, which lies west of Upper Norwood, the joints in ramps, decks and long building elevations all need attention over time. Centres like Bell Green Retail Park, 2.5 miles to the east of Upper Norwood, have mall floors and service decks whose joints carry steady traffic.

Common problems we fix in Upper Norwood
Sometimes the sealant holds but the substrate breaks away. Weak or crumbling concrete, brick or render edges give the sealant nothing sound to grip, so we tell you if the edges need repairing first.
Any of the following is a good reason to get the joints checked over:
- Sealant peeling off one face of the joint
- Water dripping through deck or ramp joints
- Debris jammed in movement joints
- Damp inside where a wall movement joint has failed
Campuses like King's College London, 3.4 miles to the north of Upper Norwood, mix old and new buildings, with movement joints wherever they meet.

What we can’t put right
Honesty saves time and money. Fresh joints won’t solve:
- Structural movement beyond what the joints were designed for (that needs a structural engineer)
- Failed waterproofing membranes on podiums, roofs or decks (a waterproofing specialist’s job)
- Joints too narrow for the movement, which need redesigning by the engineer
If you’re not sure, just speak to us on 01277 525 020 or send photos by email and we’ll give you a straight answer.
