How the quote is worked out
What shapes the price:
- Quantities, in metres or numbers
- Any access equipment needed
- The size and state of each joint
- Whether the work must be split into stages
Whether it’s a single area or a whole estate, the same things set the price: 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.
What to include in your enquiry
We can often quote from photographs and a few details. It helps to include:
- How the joints are reached, and at what height
- The asbestos register, for older buildings
- What the building is and how it’s used
- A wide shot and a close-up of the area
A good quote starts with a clear picture: the joints involved, quantities, access and the product called for. Send what you have, and we’ll arrange a site visit if anything is unclear.

Different surfaces, different methods
Commercial and mixed-use buildings
Tenants in commercial buildings need to keep trading so the work is phased.
Estate-wide resealing programmes
Housing associations and agents often manage many similar blocks. Each block is priced and scheduled in order.
Should maintenance staff do it?
Redoing a failed joint typically costs more than getting it right at the outset, because the whole bead must be removed and the faces cleaned back again. That’s why many clients bring in a specialist from the beginning.
Paperwork matters too. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and our CSCS-carded applicators are used to working under those rules.
Diagnose, treat, sign off
We begin with a short walk round with whoever looks after the building, agreeing which joints are in scope, where to start and what must stay open. Then we strip out anything that has failed, prepare every joint and seal it. 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.
- We inspect the joints, building by building, and record what has failed and why.
- A fixed quote follows, split by block or building if that suits you.
- Dates, areas and access are agreed so residents or tenants can be told in advance.
- Failed mastic is removed and the faces taken back to sound, dry material.
- Backing rod and primer go in where the joint and the product need them, then new sealant is applied and tooled.
- Each building is checked on completion and the work carries our 12-month guarantee.
Preparing the site
- Point out parking and an unloading spot
- Make sure the joints can be reached
- Send asbestos survey details if the building is pre-2000
Getting a fixed quote
Tell us about the building, the joints and when you need the work done, and we will put a fixed quote together. The easiest way is to call the office on 01277 525 020 or email the details over.

- Leaks from above rather than through a joint
- Substrate edges that need repairing first
If you’re not sure, just call the office on 01277 525 020 or email the details over and we will give you a straight answer.

Mastic sealing in West Green: the local picture
For a London block, the agent or landlord normally handles notices to residents and access to flats. Our programme follows the access you agree with residents. West Green has three care or nursing homes no more than 2 miles away. Frame mastic on care buildings is best renewed elevation by elevation, with the manager deciding timings.
If you manage student housing near a university such as American University in London, 2.1 miles south-west of West Green, the summer turnaround is the time for mastic. Site managers at schools like West Green Primary School can fit frame mastic into the summer works. Buildings close to stations like Seven Sisters station, 0.7 miles east of West Green, are often flats over shops, with frame mastic to keep sound.

Looking after the joints
After handover, these steps help:
- Prioritise elevations facing the weather
- Group repairs into a planned programme
- Make it easy for occupiers to report draughts
- Reduce knocks to communal area joints
If paintable sealant was used, decoration can follow once it has cured. Silicone typically can’t be painted, so keep decorators off it.
Failed mastic often goes unnoticed until heavy rain finds it. Acting at the first signs keeps it a straightforward reseal and the complaints that come with it.
FAQs: West Green
Do you cover business parks and estates near West Green, such as Crusader Industrial Park?
Yes, sites like Crusader Industrial Park are within our area, along with the rest of West Green. Photos and a short description are enough for a first look.
Will you take on a block within reach of Seven Sisters station?
Yes, we work for agents, landlords and housing associations with blocks of every size. Photos of each elevation help us quote accurately.
Can you follow the specification on our project?
Yes. We follow the specification, along with the manufacturer’s installation guidance.
Do you seal on top of existing sealant?
No, never. Sealing over old material is one of the classic causes of early joint failure, so it all comes out first.
Can people stay in the building while you reseal?
Residents and tenants carry on as normal. If any flats or units need access, we’ll tell you in advance so it can be arranged.
How many days will you need on site?
It depends on the scope, but the work typically takes anything from a day to a few weeks, depending on the number of buildings and joints. Larger or phased jobs take longer, and we’ll give you a timescale with the quote.
Do you guarantee the mastic work?
Every building we reseal has a 12-month guarantee. It applies to our workmanship rather than damage or problems with the frames.
