Roe Green: questions and answers
Will you take on a block within reach of Ashwell & Morden station?
Yes. Managing agents, landlords, property factors and housing associations are who this service is for. Send the address, photos of the elevations and your access arrangements, and we’ll give a fixed quote.
Is Roe Green too far out for you?
No. Places such as Roe Green are covered as much as the big towns. Our area covers London and the South East counties. We plan jobs in smaller places so return trips are kept to a minimum.
Do you work to architects’ specifications?
Yes. The specification and the manufacturer’s installation guidance are what we work to.
Do you work for managing agents and housing associations?
Yes, that’s exactly who this service is for. We work through buildings in a planned order with dates agreed in advance.
What guarantee do you give on resealing?
There is a 12-month guarantee on our workmanship and we hold public liability insurance.
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, and the duty to manage asbestos sits with the dutyholder.
Can people stay in the building while you reseal?
We plan around people living or working in the building. We agree the programme so you can notify occupiers and communal access is kept open.
Mastic sealing in Roe Green
Managing agents and housing associations normally need paperwork before anyone starts. For documents, 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, with public liability insurance. If you are dealing with old repairs sealed over failed mastic and open joints in brickwork or panels, we can put it right, on window and door perimeters on blocks, communal entrances and stairwells and communal kitchens and washrooms alike. Facilities teams, main contractors and managing agents in Roe Green tend to want the same three things: a fixed quote, no surprises on site and a 12-month guarantee behind the result.
Owners and agents with buildings around smaller places such as Roe Green tend to manage small terraces of association properties, converted barns and commercial units. Mastic around frames and on external joints wears out in time, whatever the building.
Building owners and contractors get the same cover: twelve months on the work we carried out. It doesn’t extend to damage, faults in the building or work by others, and we’re upfront about that.

Common problems we fix in Roe Green
Many failed joints were sealed without backing rod so the mastic is bonded on three sides. That three-sided adhesion stops it stretching and it tears.
These are often picked up first by site or facilities staff:
- No planned programme for sealant
- Mastic failing across several blocks on an estate
- Water getting in round frames after rain
- Patchy repairs in mismatched sealant
If your remit includes a building such as Sandon Junior Mixed and Infant School, frame and door mastic can be programmed for the holidays.
Questions to ask before you book
- Whether primer will be used where the manufacturer specifies it
- How long is the guarantee, and what does it include?
- Whether old or failed sealant will be cut out, not overlaid
- Who will actually carry out the work
Building owners, agents and FMs in Roe Green
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.
Planned maintenance programmes are welcome: resealing failed joints building by building, on a schedule that suits your budget. Roe Green can form part of a wider programme.

Block-wide mastic in Roe Green
At about 34 miles from central London, Roe Green is within reach of the capital. Commuter-belt towns tend to have plenty of managed blocks near stations and town centres. The South East is one of the drier parts of the UK. Outside work still depends on dry joints, while the elevations that take the most sun tend to show hardened mastic first.
Blocks of flats and mixed-use buildings often cluster around stations such as Ashwell & Morden station (to the north of Roe Green) and their window and balcony mastic tends to age at the same rate across a building. If you’re responsible for a building such as Church of All Saints, frame and door mastic needs the same attention as any other property.
Roe Green is in Hertfordshire. Anywhere in SG9, the process is the same: send details, get a fixed quote, we seal, and the work is guaranteed. Our Hertfordshire coverage takes in 371 places, large and small. We also cover London, some 34 miles away.

On arrival, we sign in, go through any site induction and check how permits are handled. Everything around the joints gets protected before any cutting starts, and the work usually takes anything from a day to a few weeks, depending on the number of buildings and joints. Rural sites near Roe Green may need directions, gate codes or a contact on site. Send that with the details and we will confirm the plan with the quote.

- A fixed quote covers the joints, products and order of work.
- We strip out the old sealant.
- The joints are prepared and resealed with the right product.

After the work
A few simple habits keep the new joints working:
- Check sealant joints during planned building inspections
- Plan resealing building by building rather than complaint by complaint
- Keep bins and bikes away from communal door frames
- Encourage occupiers to report problems at frames
Add mastic joints to your cyclical inspections. Check for splits, open joints, brittle mastic and lifting edges and record where they are.
Leaks at window perimeters spoil finishes and can affect frames. Resealing early keeps the job small.
Site staff or a sealant specialist?
Some joints are best left to specialists: for instance fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. Getting these wrong normally costs more in the end than doing them right.
Site maintenance staff can often handle a short internal joint. The usual problems come from preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.
When it isn’t the sealant
Part of a good diagnosis is knowing where sealant stops. We’ll tell you if the real problem is one of these:
- Old mastic suspected of containing asbestos, which must be tested and dealt with by a specialist first
- Masonry that has broken away beside the joint
- Leaks through the frame itself rather than the perimeter
If in doubt, phone 01277 525 020 or email a schedule or drawings and we will say what we think before you book.
