About our mastic sealing in Stotfold Common
We diagnose before we prescribe: 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 and backing rod used wherever a joint is deep. We work on communal entrances and stairwells, window and door perimeters on blocks and balcony and threshold joints, and the usual reasons a site gets in touch are draughts at frames across a block and brittle perimeter mastic across a building. A single leaking joint is often how a building in Stotfold Common 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.
In and around smaller places like Stotfold Common, landlords and agents often look after small groups of housing association properties, converted farm buildings and community buildings. Frame and wall-joint mastic on all of them ages and hardens.
Every job we finish is backed by a 12-month workmanship guarantee. If a joint we sealed fails because of how it was installed, we come back and put it right.

Do you need mastic sealing in Stotfold Common?
Many failed joints were sealed without backing rod so the mastic is bonded on three sides. It can’t stretch properly and it tears.
If one of these sounds familiar, it’s time for a closer look:
- Repeated reactive repairs to the same buildings
- Communal area joints that look neglected
- Draughts at frames across a block
- Estate-wide sealant that is simply worn out
Churches, halls and community buildings such as Church of Saint Guthlac 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
- Their approach to joint depth and backing
- Is the sealant right for the movement and the substrate?
- Do they follow the manufacturer’s priming guidance?
- How they handle RAMS and site documents
Building owners, agents and FMs in Stotfold Common
We work for building owners and managing agents on everything from one building to a spread of sites. Several sites can go on one quote, so there’s one set of paperwork to deal with.
When you manage a building on behalf of an owner, clear figures and clear communication matter. We quote a fixed sum, confirm the scope and walk the finished work with you or your representative, plus a 12-month guarantee.
What the job involves on each surface
External movement joints
Movement joints are cleaned out, backed with rod and resealed with a sealant of the right movement class.
Commercial and mixed-use buildings
Commercial occupiers typically stay open during the work so the work is phased.
After the work
Keep the joints in good shape with a few simple steps:
- Share the asbestos register when you send details
- Prioritise elevations facing the weather
- Ask residents or tenants to report leaks and draughts early
- Include mastic in your cyclical inspections
Encourage occupiers to report water or draughts at frames. Early reports catch failures before damage spreads.
Planned resealing is easier to budget than emergency repairs. We can quote buildings in priority order and work down the list.
Questions we’re asked in Stotfold Common
Is Stotfold Common off your patch?
Not at all: smaller places are covered as well as towns. We work across Greater London and the South East. Good photographs up front let us bring everything on the first visit.
Can one quote cover a number of our buildings near Stotfold Common?
Yes. Portfolio-wide programmes are a regular request. Residents are given notice through you, and the work moves building by building.
What guarantee do you give on resealing?
A 12-month guarantee covers our work. It applies to our workmanship rather than damage or problems with the frames.
Do you work for managing agents and housing associations?
Yes, that’s exactly who this service is for. Buildings are scheduled in turn so you can plan around it.
How do you handle work on occupied blocks?
Residents and tenants carry on as normal. If any flats or units need access, we’ll tell you in advance so it can be arranged.
How long will the new sealant last?
There’s no fixed lifespan: movement, exposure, cleaning, traffic and the product all play a part. Treat them as maintenance items and inspect them regularly.
Can you seal joints high up on a block?
We talk through access for each building when we quote. Tell us the number of storeys and whether scaffold or other access is planned, and we will tell you how we’d approach it.
Diagnose, treat, sign off
A typical day starts with protection: masking tape along the joint edges and sheeting over anything nearby. On site, the work usually takes one or more days per building, depending on the joint lengths and the access, and our waste is bagged and taken away as we go. Jobs in and around smaller places like Stotfold Common are usually planned as a single visit, so we ask for photos and rough sizes first. Then the right materials arrive with us.
- We inspect the joints, building by building, and record what has failed and why.
- We send a fixed quote that sets out the joints, the products and the programme.
- Dates, areas and access are agreed so residents or tenants can be told in advance.
- Failed mastic is removed and the faces taken back to sound, dry material.

Why deal with it now?
Open external joints let water into walls and around frames. Damp patches, stained plaster and decorating claims can follow and those cost far more to put right. Around Stotfold Common, it’s better to renew all the failing joints at once, rather than one at a time. Send photos of each area and we’ll quote for the lot.
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.
