Mastic sealing for Lions Green sites
Photos, a specification or a quick description of the joints is enough to start a fixed quote.
Surface by surface
Estate-wide resealing programmes
Using the same products throughout keeps the estate consistent and easier to manage.
Tenement and older buildings
Older buildings, including Scotland’s sandstone tenements, have their own joint details. The material either side of the joint shapes the product choice.
Mastic sealing in Lions Green
There isn’t one mastic for every joint on a building. Window perimeters and external joints often take a low-modulus neutral-cure silicone, while hybrid polymer sealants grip many materials and are often paintable. We’ll confirm the colours available for the specified product. If you have leaks at window and door perimeters and failed external movement joints, we can put it right, on communal entrances and stairwells, balcony and threshold joints and shopfronts below residential blocks alike. One point of contact handles commercial sealant work in Lions Green from the first photos to the final walk-round, whether it’s one building or several.
For owners with a single building near Lions Green, we plan to finish in one visit where possible. Photos of each elevation help us quote accurately.
We stand by our work with a 12-month guarantee. It covers how we prepared and applied the sealant, and we come back if anything isn’t right.

When to call us in Lions Green
The edges of the material itself sometimes break away, such as crumbling render, brick arrises or frame edges. If the edges are unsound, we say so before quoting the sealing.
These are often picked up first by site or facilities staff:
- Damaged joints in communal entrances and corridors
- No planned programme for sealant
- The same joint failures repeated across a portfolio
- Leaks at window and door perimeters
Historic properties like Horselunges Manor, 4 miles south of Lions Green, show the age of some local stock, where frame mastic must suit soft brick or stone.
What your quote should include
- Can the work be phased to keep areas open?
- Are they CHAS accredited or on Constructionline?
- Who will actually carry out the work
- Whether old or failed sealant will be cut out, not overlaid
Questions we are asked in Lions Green
Can one quote cover a number of our buildings near Lions Green?
Yes, we quote for single buildings and for programmes across several blocks. We can phase the programme to suit your budgets and notice periods.
Does your area include sites such as Merrydown Business Park, near Lions Green?
Yes, sites like Merrydown Business Park are within our area, along with the rest of Lions Green. To start, just speak to us on 01277 525 020 or send photos by email with the unit, the joints involved and your access times.
Do you guarantee the mastic work?
Our workmanship carries a 12-month guarantee, backed by public liability insurance.
Do you supply RAMS and insurance details?
Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we’ll confirm with the quote. We are CHAS accredited and a Constructionline member.
When can the area be used after sealing?
Curing time varies by product, and we confirm it on the day, and flag anything to keep off until it has cured.
How many days will you need on site?
The duration is planned around your programme and the access we’re given. You will have an expected duration with the quote.
Can weather delay the job?
Outside, yes. The joint has to be dry and within the product’s temperature range, so damp, frosty or very cold days can stop external work. Internal work is rarely affected.
Looking after the joints
Every sealant joint needs some looking after, and how long they last depends on how they’re treated. We suggest:
- Check the asbestos register before any old mastic is disturbed
- List the paperwork your organisation requires when you send details
- Keep a record of when each building was resealed
- Make mastic part of routine maintenance checks
Keep records of when each building was resealed. It helps plan the next round and gives you a history.
Failed mastic often goes unnoticed until heavy rain finds it. Acting at the first signs keeps it a straightforward reseal and saves internal repairs.
For owners and agents in Lions Green
Lions Green lies roughly 41 miles out from central London. Within reach of London, blocks run by agents and associations are common around stations, and window and balcony mastic on them tends to age at the same rate. Lions Green sits in one of the drier corners of the country, the South East. Even so, frame mastic only goes on in dry, workable conditions, and south- and west-facing elevations, which take the most sun and rain, often age first.
Older community buildings, The Parish Church of All Saints among them, often have frames of mixed ages whose mastic varies. Landlords with units on estates such as Merrydown Business Park, 1.2 miles south-east of Lions Green, can bring frame, door and external mastic across several units into one programme.

Our process
Before we leave any area, the masking comes off, the area is cleaned and every joint is checked. If an area should be left alone while the sealant cures, we say how long and put signs out. Rural sites near Lions Green may need directions, gate codes or a contact on site. Add it to your enquiry and we will build it into the plan.
- First comes a look at the joints and, for older buildings, the asbestos records.
- The products and programme are set out in a fixed quote.
- Failed mastic is removed completely.
- Joint faces are cleaned, backed and resealed.
- Buildings are completed in turn.
Getting the site ready
- Make sure the joints can be reached
- Send any specification or drawings in advance
- Send asbestos survey details if the building is pre-2000

How the quote is worked out
What shapes the price:
- How accessible the joints are
- How much there is to seal
- Removal of failed or old sealant
- The size and state of each joint
The work involved drives the cost: stripping out, preparation, sealing, access and phasing. Call for a fixed quote and we will explain how it’s made up.
What we need to price the job
For an accurate fixed quote, we need to understand the site. Useful things to include:
- Anything awkward about access or site hours
- When you need the work done
- A wide shot and a close-up of the area
- Whether an asbestos survey exists
A handful of photographs and a postcode is the fastest way to a quote. Upload them with the quote form, or call the office on 01277 525 020 or email drawings and photos to discuss it first.
When something else is needed
Honesty saves time and money. Fresh joints won’t solve:
- Materials that need asbestos testing before work
- Leaks from above rather than through a joint
- Cracked or crumbling render, brick or stone at the joint edges (we will tell you if so)
If in doubt, call 01277 525 020 or email the details over and we will say what we think.
