How we handle mastic sealing in Hockenden
Across Hockenden and the rest of Greater London, we work the same way: you send details, we return a fixed quote, the joints are resealed and the 12-month guarantee follows. A list of buildings, a few photos and approximate joint numbers are enough for a quick quote or we can visit. We work on window and door perimeters on blocks, balcony and threshold joints and external wall and movement joints, and the failures we are asked to look at most are complaints coming in block by block and a mix of products and colours from past repairs. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, the work in Hockenden is the same: failed joints cut out, faces prepared and the right sealant laid to the right depth.
Across Greater London, Hockenden 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.
Every job is signed off with a 12-month guarantee. The promise is simple: if our work fails within that year, we put it right.

Surface by surface

Hockenden: questions and answers
Can you work in a care home near Hockenden with residents in?
Yes, with the manager deciding the order and timing of rooms. Any site rules, from signing in to infection control, are agreed before we start.
Do you work for managing agents with blocks near Swanley 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 will quote and plan to suit.
Is asbestos a concern with old mastic?
In older buildings, old mastic can contain asbestos. We check the asbestos register or survey before disturbing it, and if it’s suspected, work stops until it’s tested.
How do you choose the sealant?
If the job is specified, we follow the specification. Otherwise, we recommend a product to suit the joint’s movement, the substrate and the conditions, following the manufacturer’s guidance.
How long does a job like this take?
It depends on the scope, though a typical visit usually 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 will give you a timescale with the quote.
What about access for upper-floor joints?
It depends on the building. How upper joints are reached is agreed before work is booked so the fixed quote reflects it.
What paperwork can you provide?
Let us know your requirements: tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we’ll confirm with the quote. We hold CHAS accreditation and Constructionline membership.
Leave it or put it right?
Piecemeal repairs over the years often leave mismatched sealant. Resealing a whole building gives a consistent finish and one 12-month guarantee. In Hockenden, each extra visit means more notices, permits and disruption, so cutting the old sealant out fully and doing it right once is the better route.
A quote for mastic joints depends on how many there are, their condition and the access, and any specification that applies. Ask us for a fixed quote.

When it isn’t the sealant
Not every problem is a sealant problem, and we’re upfront when that’s the case. It won’t fix:
- Leaks through the frame itself rather than the perimeter
- Asbestos-containing sealant, which we don’t remove
- Broken glass or failed sealed units
If you’re not sure, just speak to us on 01277 525 020 or send details through our quote form and we’ll give you a straight answer before you book.

What affects the price in Hockenden
There’s no standard rate for sealant work, because every site is different. What we take into account:
- Site requirements such as inductions and permits
- Backing rod, priming and other preparation
- The total length or number of joints
- Specialist products, such as fire-rated or hygienic sealants
We don’t publish prices, since every building and every scope is different. For a fixed figure, call for a quote and we will price your job on its own details.
What we need to price the job
We can often quote from photographs and a few details. Please tell us:
- Any specification or named product
- A wide shot and a close-up of the area
- When you need the work done
- Approximate linear metres or a joint schedule

Do you need mastic sealing in Hockenden?
We often find joints filled solid with no backing rod so the mastic is bonded on three sides. It can’t stretch properly and it tears.
Things that usually lead to an enquiry:
- Old repairs sealed over failed mastic
- Cracked, hardened mastic round windows on a block
- Worn sealant at communal door frames
- Draughts at frames across a block
Student accommodation around universities such as University of Greenwich Avery Hill Campus (4.4 miles north-west of Hockenden) is normally managed block by block, which suits a planned mastic programme.
Questions to ask before you book
- How long is the guarantee, and what does it include?
- Whether old or failed sealant will be cut out, not overlaid
- Can the work be phased to keep areas open?
- The named product and why it was chosen
How a job runs
Before any cutting starts, the area is protected: masking tape along the joint edges and sheeting over anything nearby. On site, the work typically takes a few days for most blocks, with larger programmes scheduled building by building, and our waste is bagged and taken away as we go. Most London premises stay occupied while we are on site, so zones and timings are agreed with whoever manages the building. Areas are handed back as each section is finished.
- A building-by-building inspection lists the failed joints.
- The quote is fixed and split as suits you.
- We agree the programme and dates with you.
- Old mastic is removed and the joint faces prepared.
- Joints are resealed and tooled.
- Each building is checked and signed off with the 12-month guarantee.
Before we start on site
- Send your site hours and access windows
- Share the asbestos register for older buildings
- Let building users know which areas are affected
