Block-wide mastic in Rushlake Green
At about 42 miles from central London, Rushlake Green is within reach of the capital. Around the capital’s commuter belt, managing agents look after many blocks close to stations and town centres, and window and balcony mastic on them tends to age at the same rate. Rushlake Green is in the South East, one of the UK’s drier regions. Outside mastic still needs a dry joint and the right temperature, and elevations facing the sun and the prevailing weather are usually where frame mastic ages first.
For a school such as Heathfield Community College, perimeter mastic on windows and doors is a holiday job. Property owners at sites such as Swife Business Park, 2.7 miles to the north of Rushlake Green, can have mastic renewed between lettings.

About our mastic sealing in Rushlake Green
Treatment starts with a proper look: what has failed, what caused it and whether new sealant will actually solve it. Failed mastic is stripped, the faces taken back to sound material, primed where the manufacturer specifies and resealed, with backing rod setting the depth where it’s needed. We work on window and door perimeters on blocks, communal kitchens and washrooms and balcony and threshold joints, and what we’re called in for most is worn sealant at communal door frames and damp patches beside frames. Whoever orders the work in Rushlake Green, the brief is usually the same: a clear scope, tidy work and joints that don’t fail again.
In and around smaller places like Rushlake Green, landlords and agents often look after small groups of housing association properties, converted farm buildings and community buildings. Mastic around frames and on external joints wears out in time, whatever the building.
Building owners and contractors get the same cover: a 12-month guarantee on our workmanship. Faults in the structure, damage and other trades’ work fall outside it, and we say so plainly.

What sealant work can’t fix
A few problems need another trade or a different fix, and we say so rather than covering them up:
- Leaks through the frame itself rather than the perimeter
- Old mastic suspected of containing asbestos, which must be tested and dealt with by a specialist first
- Broken glass or failed sealed units
If you’re not sure, just phone 01277 525 020 or use the quote form and we will give you a straight answer before you book.
What we seal

Rushlake Green: questions and answers
Can you quote for mastic across several buildings in and around Rushlake Green?
Yes. Planned programmes across a building, block or estate are a core part of this service. Send the addresses and photographs and we will give a fixed quote.
Will you take on work at estates like Swife Business Park, close to Rushlake Green?
Yes. Estates, retail parks and business parks around Rushlake Green, Swife Business Park among them, are all within reach. Photos and a short description are enough for a first look.
What paperwork can you provide?
Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we will confirm with the quote. We hold CHAS accreditation and Constructionline membership.
Which sealant will you use?
Where there’s a specification, we use the product it names. If not, we choose for the movement, the surfaces and the conditions, in line with the manufacturer’s guidance.
Can you take on resealing for a block portfolio?
Yes, that’s exactly who this service is for. Buildings are scheduled in turn with dates agreed in advance.
Do you work in Rushlake Green?
Yes. We cover Rushlake Green, and the simplest way to start is to speak to us on 01277 525 020 or email the details over.
How do you reach windows on upper floors?
We talk through access for each building when we quote. Tell us the building height and any access already in place, and we will tell you how we’d approach it.
Keeping the joints sound
A few simple habits keep the new joints working:
- Share your contractor requirements early
- Start inspections with the most exposed faces
- Make it easy for occupiers to report draughts
- Make mastic part of routine maintenance checks
Keep bins, bikes and deliveries away from low-level joints where you can. Knocks cause many early failures in communal areas.
Joints on a building age together so a single failure is a sign to check the rest. Doing them together saves going back again and again.
On site: what to expect
Before any cutting starts, the area is protected: masking tape along the joint edges and sheeting over anything nearby. On site, the work normally takes a day or two for a single block, longer for an estate programme, and our waste is bagged and taken away as we go. If others near Rushlake Green need work, visits can be combined. A fixed quote is given before anything starts.
- 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.
- The programme is fixed with you, including dates you can pass on to residents or tenants.
- Failed mastic is removed and the faces taken back to sound, dry material.
- Deep joints get backing rod, faces are primed if the manufacturer specifies it, then the joint is sealed and tooled.
- Completed joints are inspected and carry a 12-month workmanship guarantee.
Before we start on site
- Move anything stored against the joints
- Let building users know which areas are affected
- Agree which areas must stay open

Advice
When to call us in Rushlake Green
Frames, panels and masonry expand and contract through the year, and every joint has to stretch and squeeze with them. If the joint or the product wasn’t suited to the movement, it splits long before it should.
Site and facilities staff are often the first to spot these:
- Movement joints with sealant missing
- Damp patches beside frames
- The same joint failures repeated across a portfolio
- Worn sealant at communal door frames
Churches, halls and community buildings such as The Parish Church of St Mary are looked after by trustees and committees like any other owner, and their frames, doors and external joints need mastic renewed in time.
Questions to ask before you book
- How they handle RAMS and site documents
- Health and safety accreditation such as CHAS
- Which product they’ll use, and why it suits the joint
- How they’ll work around occupants
Cost factors for mastic joints
The price varies from site to site. It mainly depends on:
- Which sealant the job calls for
- Whether the work must be split into stages
- Joint width, depth and condition
- Quantities, in metres or numbers
Pricing mastic joints depends on how many there are, their condition and the access, plus any specification you are working to. Ask us for a fixed quote.
What to include in your enquiry
A few photographs plus some basic facts will normally do. It helps to include:
- Drawings or a marked-up plan, if available
- Photos of the joints, close up and from further back
- Whether an asbestos survey exists
- The product your specification calls for
The quickest route to a quote is a few photos and the site postcode. Upload them with the quote form, or give us a call on 01277 525 020 or use the quote form to discuss it first.
Why it’s worth doing now in Rushlake Green
Failed perimeter mastic lets cold air in around frames, and they often blame the windows. Resealing the perimeters is often the simpler fix when the frames themselves are sound. Converted and older buildings near places like Rushlake Green tend to move, and aged sealant cracks. The right product, sized to the joint, copes much better.
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.
