Mastic sealing in Hedsor, done properly
In buildings from before 2000, some old mastics contain asbestos. We check the asbestos register or survey before any old sealant is cut out, and work stops for testing if there’s any doubt. We don’t remove asbestos-containing materials. If you have repeated reactive repairs to the same buildings and leaks at window and door perimeters, we can put it right, whatever the surface. Whoever orders the work in Hedsor, the brief is typically the same: a clear scope, tidy work and joints that don’t fail again.
Around smaller places like Hedsor, older walls fitted with newer windows are a familiar sight. The mastic needs to suit an irregular masonry face and the look of the building.
Work we carry out comes with a 12-month guarantee. Should something we installed fail, speak to us on 01277 525 020 or email drawings and photos and we will come back to it.

Different surfaces, different methods
Window and door perimeters on blocks
We normally work through a block’s windows in a planned order. Access is agreed with you before the quote is fixed.
Planned maintenance
Resealing can be scheduled alongside other planned works, building by building.
Diagnose, treat, sign off
A typical day starts with protection: masking tape along the joint edges and sheeting over anything nearby. The work itself typically takes a day or two for a single block, longer for an estate programme, and we clear our waste as we work. Jobs in and around smaller places like Hedsor are typically planned as a single visit, so we ask for photos and rough sizes first. Then the right materials arrive with us.
- Each block or building is walked and the failed joints recorded with the likely cause.
- A fixed quote follows, split by block or building if that suits you.
- 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.
- Backing rod and primer go in as the joint requires, then the new bead is placed and tooled.
- Finished joints are looked over and the 12-month guarantee confirmed.
Getting the site ready
- Explain the parking and delivery arrangements
- Warn occupants and staff about the work

Advice
Looking after buildings in and around Hedsor
Hedsor 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. Hedsor is about 26 miles from central London. Within reach of London, blocks run by agents and associations are common around stations; their frame mastic often ages block-wide.
Landlords with units on estates such as Soho Mills Industrial Estate, 0.5 miles north-west of Hedsor, can bring frame, door and external mastic across several units into one programme. Student blocks close to universities like Buckinghamshire New University, 4.6 miles north-west of Hedsor, are easiest to work on between tenancies.
Hedsor is about 3 miles south-west of Beaconsfield, in Buckinghamshire. Hedsor sits inside our coverage and the rest of Buckinghamshire, and jobs here get the same fixed quote and 12-month guarantee as anywhere else. Hedsor is one of 308 places in Buckinghamshire on our list for mastic joints. Reading is covered too, some 15 miles away.
Work on mastic joints is covered throughout HP10 and SL8, for business premises of every kind. We cover commercial and managed buildings on Kiln Fields, Kiln Lane and Broad Lane and the roads nearby. Close to Hedsor, our area also takes in Wooburn (1 mile north), Berghers Hill (1 mile north-east), Wooburn Common (1 mile north-east), Wooburn Green (2 miles north) and Littleworth Corner (2 miles south-east). A short drive away, we cover High Wycombe (5 miles north-west), Chesham (10 miles north), Marlow (4 miles west), Amersham (8 miles north-east), Beaconsfield (3 miles north-east) and Chalfont St Peter (6 miles east).
What’s near Hedsor
Locally, jobs take us to sites close to Chequers Inn and Wye Valley School and the streets around them. The nearest railway station is Bourne End station, about 1 mile west of the centre. Nearby you will also find High Wycombe Castle (4.7 miles north-west) and Marlow Community Hospital (3.6 miles west). Green spaces nearby include Warren Nature Reserve and Taplow Lake.
When it isn’t the sealant
We check first that sealant really is the fix. It won’t put right:
- Leaks from above rather than through a joint
- Glazing that needs replacing
- Leaks through the frame itself rather than the perimeter
Not sure which it is? You can ring 01277 525 020 or email drawings and photos and we will tell you honestly before you book.
Surfaces we seal
- Shopfronts below residential blocks
- Communal kitchens and washrooms
- Communal entrances and stairwells
- Window and door perimeters on blocks
- Balcony and threshold joints
- External wall and movement joints
What affects the price in Hedsor
To price the job, we consider:
- How accessible the joints are
- Site requirements such as inductions and permits
- How much existing material needs removing
- Location, for remote and island sites
The specified product makes a difference, as does the preparation each joint needs, from cutting out to priming and backing rod. Access, phasing and site requirements come into it too.
Sending details for a quote
Good information means a firmer quote. Helpful details to send:
- Anything awkward about access or site hours
- What the building is and how it’s used
- The asbestos register, for older buildings
- Clear photographs of the problem areas
Quotes are fixed against the scope you send, so you know the figure before anyone is on site. To ask for one, give us a call on 01277 525 020 or email drawings and photos.
FAQs: Hedsor
Can you work at a site such as Soho Mills Industrial Estate, by Hedsor?
Yes. Our area takes in Hedsor and its surroundings, with estates and business parks such as Soho Mills Industrial Estate included. To start, just ring 01277 525 020 or email drawings and photos with the unit, the joints involved and your access times.
Is Hedsor too small for you to travel to?
No. Places such as Hedsor are covered as much as the big towns. London and every South East county are within our area. We plan jobs in smaller places so return trips are kept to a minimum.
Do you work for managing agents and housing associations?
Yes, block and estate work is a core part of what we do. We work through buildings in a planned order with dates agreed in advance.
How many days will you need on site?
We plan the time on site around your programme and access. We’ll give you an estimate of time on site when we quote.
Do you check for asbestos in old sealant?
We don’t remove asbestos-containing materials. Anything suspect is tested before we carry on in line with the dutyholder’s asbestos management.
How long before the joints can be used?
The product and site conditions decide that. Some products skin over quickly but need longer to cure fully, so we’ll confirm the curing time on the day.
What will the job cost?
Each job is quoted on its own details. For yours, call 01277 525 020 or email a schedule or drawings.

Other services in Hedsor
Do you need mastic sealing in Hedsor?
Topping up old mastic is a common shortcut. New sealant won’t grip failed sealant and the repair soon fails.
These are often picked up first by site or facilities staff:
- Old repairs sealed over failed mastic
- Draught complaints from residents or tenants
- Brittle perimeter mastic across a building
- Leaks at window and door perimeters
If you look after a block within reach of Bourne End station, 1 mile to the west of Hedsor, frame and balcony mastic can be renewed on one programme.
