Common questions from West Norwood clients
Can you work in a London building with booked loading and goods-lift slots?
Yes, we plan every London job around the building’s own access rules. The building manager’s rules go straight into our method. The ULEZ covers the whole of Greater London, which we allow for
Will you take on a block within reach of West Norwood station?
Yes. Managing agents, landlords, property factors and housing associations are who this service is for. We work to your notice and access arrangements.
Does the weather affect the work?
For external joints, yes. The joint has to be dry and within the product’s temperature range, so frost, rain or cold mornings can delay outside work. Inside work is seldom held up.
What guarantee do you give on resealing?
A 12-month guarantee covers our work. It applies to our workmanship rather than damage or problems with the frames.
Can you follow the specification on our project?
Yes. Send it with your enquiry, and we will price the work to it, flagging anything that needs clarifying.
Is it fine to apply new sealant on top of old?
No. We cut the old material out and clean the joint back before sealing, since fresh sealant will not bond reliably to aged material.
How long do sealant joints last?
There’s no fixed lifespan: movement, exposure, cleaning, traffic and the product all play a part. Sealant joints are maintenance items, so inspect them regularly.
Mastic sealing in West Norwood
For over 20 years we have resealed joints for owners, agents and landlords. Our applicators are CSCS-carded and we hold public liability insurance. Resealed mastic joints in West Norwood carry our 12-month guarantee. The enquiries we see most involve damaged joints in communal entrances and corridors and mastic failing across several blocks on an estate, on window and door perimeters on blocks, external wall and movement joints and communal kitchens and washrooms. Whether you call it commercial sealant work, mastic application or joint sealing, in West Norwood it comes down to the same thing: the right product in a properly prepared joint.
Across Greater London, West Norwood included, the ULEZ applies, and parking and loading rules differ from street to street. For a block or estate, it helps to know where we can park and stage materials.
The 12-month guarantee covers our workmanship: the preparation, the sealing and the tooling. It doesn’t extend to damage, other trades’ later work or movement the joint was never designed to take.

Blocks and managed buildings in West Norwood
The 2 miles around West Norwood include five care or nursing homes. Frame mastic on care buildings is best renewed elevation by elevation, with the manager deciding timings. In London, mastic work on a block goes through the managing agent or landlord, with notice to residents. Our programme follows the access you agree with residents.
Churches, halls and community buildings such as West Norwood Congregational Church are looked after by trustees and committees like any other owner, and their frames, doors and external joints need mastic renewed in time. Schools and community buildings such as St Luke's Church of England Primary School need frame and external mastic kept sound like any building.

When it isn’t the sealant
A few problems need another trade or a different fix, and we say so rather than covering them up:
- Broken glass or failed sealed units
- Failed window or door frames, which need a window contractor
- Roof leaks, gutters or failed flashings that aren’t sealant joints
Not sure which it is? You can give us a call on 01277 525 020 or email a schedule or drawings and we will tell you honestly.

Signs you need mastic sealing in West Norwood
We often find joints filled solid with no backing rod, so the mastic is glued to the joint bottom too. It can’t stretch properly and splits as the building moves.
Look out for the following:
- No planned programme for sealant
- Draughts at frames across a block
- Open joints in brickwork or panels
- Damaged joints in communal entrances and corridors
For agents with blocks near West Norwood station, 0.5 miles north-west of West Norwood, a block-wide mastic programme deals with frames, balconies and entrances in one go.

Advice
Why it’s worth doing now in West Norwood
Reacting to every complaint means sending someone out block by block. A planned programme treats each building once and is simpler to manage and budget. Access in London is hard enough to arrange once, so while access is arranged it pays to renew all failing joints, not just the worst.
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’ll put a fixed figure on it.
What you get with us
- Commercial sealant work since 2005
- Standard and matched colours in many product ranges
- 12-month guarantee on workmanship
- Constructionline member
After the work
Once the work is signed off, a little attention goes a long way:
- Check the asbestos register before any old mastic is disturbed
- Check sealant joints during planned building inspections
- Group repairs into a planned programme
- Mention RAMS, insurance or CSCS requirements up front
Include sealant in planned building inspections. Check for splits, open joints, brittle mastic and lifting edges, and note the building and elevation.
One failed perimeter typically means others on the same building are close so a single failure is a sign to check the rest. A planned reseal saves repeated visits.
Quoting for work in West Norwood
Your fixed quote is built from the real scope. It allows for:
- Phasing around occupants
- How accessible the joints are
- Which sealant the job calls for
- Distance, for remote addresses
The product called for affects the cost, and so does the preparation, such as cutting out, priming or new backing rod. Access, phasing and site requirements come into it too.
