About our mastic sealing in Totteridge
Managing agents and housing associations usually need paperwork before anyone starts. Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we’ll confirm with the quote. We’re a Constructionline member and CHAS accredited, and we carry public liability insurance. We work on balcony and threshold joints, window and door perimeters on blocks and shopfronts below residential blocks, and the usual reasons a site gets in touch are damaged joints in communal entrances and corridors and no planned programme for sealant. For commercial sealant work in Totteridge, you deal with one contact from quote to sign-off, for single jobs and planned programmes alike.
For managing agents in Totteridge, resident access, notice periods and the building’s rules shape the job. Work is planned with the agent so residents get notice and access is arranged in advance.
Whoever the client is, the cover is the same: twelve months on the work we carried out. Faults in the structure, damage and other trades’ work fall outside it, and we say so plainly.

Keeping the joints sound
Once the work is signed off, a little attention goes a long way:
- List the paperwork your organisation requires when you send details
- Check sealant joints during planned building inspections
- Track which buildings were done and when
- Keep bins and bikes away from communal door frames
Keep records of when each building was resealed. That makes future programmes easier to plan and shows what was done.
The longer failed joints are left, the more likely the substrate edges break up. Once that happens, repairs come before resealing and the job grows.

Hospitality, education, healthcare, office and retail clients book us directly too. The work is planned around how the building runs, so the building keeps working while we do.
If you look after buildings for someone else, clear figures and clear communication matter. You get a fixed quote, an agreed scope and a walk round at the end.
What sets the cost
There’s no standard rate for sealant work, because every site is different. What we take into account:
- Joint width, depth and condition
- Phasing around occupants
- Removal of failed or old sealant
- Which sealant the job calls for
Every site prices differently: joint size, product, access and site hours all play a part. Send the details and a fixed figure follows.
Sending details for a quote
Good information means a firmer quote. Helpful details to send:
- Whether the building will be occupied during the work
- Any specification or named product
- Photos of the joints, close up and from further back
- Asbestos survey details if the building is older

Common questions from Totteridge clients
Do you work in London buildings with loading restrictions?
Yes. Booked loading bays, goods lifts and permit-to-work systems are normal for London jobs. Say when the building is occupied and when it’s quiet, and we will plan accordingly. All of Greater London is inside the ULEZ, and our planning allows for it
Do you work for managing agents with blocks near Oakleigh Park station?
Yes, and several blocks can go on one quote. Give us the building’s details and say how residents are notified, and we will quote and plan to suit.
Is Totteridge in your area?
Yes. We cover Totteridge, within our coverage of Greater London, South East England and Scotland. For a quote, ring 01277 525 020 or email us.
How long does a job like this take?
The duration is planned around your programme and the access we are given. We’ll give you an estimate of time on site when we quote.
How long will the new sealant last?
There isn’t a single answer, since movement, weather, cleaning and use all affect it. Regular checks let you plan resealing before leaks or damage.
How long before the joints can be used?
Curing time varies by product, and we confirm it on the day.
Will residents or tenants be disturbed?
Residents and tenants carry on as normal. We flag any areas that need internal access well before the dates so it can be arranged.
From enquiry to sign-off
Before we leave any area, the masking comes off, the area is cleaned and every joint is checked, ready for your sign-off. If an area should be left alone while the sealant cures, we say how long and put signs out. All of Greater London is in the ULEZ, and kerbside space in Totteridge can be scarce. If there’s a loading bay, a car park or a permit we can use, tell us when you send details.
- We check the asbestos register for older buildings and look at the joints.
- A fixed quote covers the joints, products and order of work.
- Failed mastic is removed completely.
- The joints are prepared and resealed with the right product.
- We finish each building before moving to the next.
Before we start on site

Common problems we fix in Totteridge
Many failed joints were sealed without backing rod so the mastic is bonded on three sides. It can’t stretch properly and splits as the building moves.
Most enquiries start with something like this:
- Damaged joints in communal entrances and corridors
- Cracked, hardened mastic round windows on a block
- Mastic failing across several blocks on an estate
- Draught complaints from residents or tenants
If you manage student housing near a university such as Middlesex University (3.2 miles south-west of Totteridge), the summer turnaround is the time for mastic.

When it isn’t the sealant
We check first that sealant really is the fix. It won’t put right:
- Glazing that needs replacing
- Roof leaks, gutters or failed flashings that aren’t sealant joints
- Old mastic suspected of containing asbestos, which must be tested and dealt with by a specialist first
