Mastic sealing in Crow's Green
Most buildings come with mastic joints nobody has looked at since handover, and it ages quietly: window perimeters, door frames, external joints and communal junctions all rely on it. Once it cracks, hardens or comes away, draughts and water find a way in along with complaints. If you’re dealing with mastic failing across several blocks on an estate and a mix of products and colours from past repairs, we can help. A single leaking joint is often how a building in Crow's Green first comes to us: we check the joints around it and give you an honest view of what needs doing now and what can wait.
For owners with a single building near Crow's Green, we plan to finish in one visit where possible. Send photographs of the frames and joints and we will give a fixed quote.
We stand by our work with a 12-month guarantee. That covers our preparation and application.

Maintenance after handover
Every sealant joint needs some looking after, and their life depends on movement, exposure, cleaning and use. We suggest:
- Plan resealing building by building rather than complaint by complaint
- Check the asbestos register before any old mastic is disturbed
- Look at the sunniest and most exposed elevations first
- Protect low-level joints in entrances
If paintable sealant was used, decoration can follow once it has cured. Non-paintable silicone shouldn’t be painted over unless told otherwise.
Joints on a building age together, so it pays to look at the whole elevation. A planned reseal saves repeated visits.
On site: what to expect
Working in a building that stays open takes some planning. We sign and contain the area we are in, with routes through the building left open and move on in phases so staff and visitors can carry on around us. Jobs in and around smaller places like Crow's Green are typically planned as a single visit, so we ask for photos and rough sizes first. Then the right materials arrive with us.
- We inspect each building and record the joints that have failed.
- 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.
- New sealant goes in with backing rod and primer where needed.
- Each building is checked and signed off with the 12-month guarantee.
Getting the site ready
- Let building users know which areas are affected
- Have the specification and drawings to hand
- Explain the parking and delivery arrangements

- Failed external movement joints
- Draughts at frames across a block

Crow's Green: questions and answers
Can you work at a site such as Goulds Farm Industrial Estate, by Crow's Green?
Yes. Our area takes in Crow's Green and its surroundings, with estates and business parks such as Goulds Farm Industrial Estate included. Photos and a short description are enough for a first look.
Is Crow's Green off your patch?
No. Places such as Crow's Green are covered as much as the big towns. We cover Greater London and the counties of the South East. Send photographs and a list of what needs doing, and we’ll plan the job to need as few trips as possible.
What’s the quickest route to a quote?
You can use the quote form on this site; alternatively, give us a call on 01277 525 020 or email a schedule or drawings. Photos, drawings or a joint schedule help us quote quickly.
Do you check for asbestos in old sealant?
We don’t remove asbestos-containing materials. If old sealant is suspected, work stops until it’s tested in line with the dutyholder’s asbestos management.
Can you follow the specification on our project?
Yes. We follow the specification, along with the manufacturer’s installation guidance.
How long do sealant joints last?
There’s no fixed lifespan: movement, exposure, cleaning, traffic and the product all play a part. Sealant joints are maintenance items, so inspect them regularly.
Will you just go over the old sealant?
No. We cut the old material out and clean the joint back before sealing, since fresh sealant will not bond reliably to aged material.
Looking after buildings in and around Crow's Green
Crow's Green is about 37 miles from central London. Commuter-belt towns tend to have plenty of managed blocks near stations and town centres. Crow's Green sits in one of the drier corners of the country, the South East. External mastic still waits for dry faces and the right temperature, and south- and west-facing elevations, which take the most sun and rain, often age first.
Property owners at sites such as Goulds Farm Industrial Estate (to the south-east of Crow's Green) can have mastic renewed between lettings. If you’re responsible for a building such as Church of St James, frame and door mastic needs the same attention as any other property.

For managing agents and facilities managers
FMs need a contractor who is easy to get on site. Tell us what site paperwork you need, such as RAMS, an insurance certificate or CSCS details, and we’ll confirm with the quote.
Housing associations and managing agents often need work done across blocks and communal areas. Work can be phased so residents and staff keep access throughout, and each stage is agreed with your contact.
Should maintenance staff do it?
Putting right a botched joint often costs more than sealing it well at the start, because the whole bead must be removed and the faces cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.
General builders and handymen seal joints, but it isn’t their main trade. A specialist prepares properly, controls joint depth and picks a product with the right movement class, which is what makes a joint last.
