Mastic sealing in Sedrup, done properly
For blocks and buildings in Sedrup and across Buckinghamshire, the process is the same: you send details, we return a fixed quote, the joints are resealed and the 12-month guarantee follows. Addresses, photographs of typical joints and a rough idea of quantities let us give a quick quote, and site visits can be arranged. If you’re dealing with occupiers reporting cold air round windows and open joints in brickwork or panels, we can put it right. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: on jobs in Sedrup, preparation and product choice get the time they need.
Owners and agents with buildings around smaller places such as Sedrup tend to manage small terraces of association properties, converted barns and commercial units. Frame and wall-joint mastic on all of them ages and hardens.
Every job ends the same way: guaranteed. You get a 12-month guarantee on our workmanship, and we explain exactly what that covers when we quote.

What sets the cost
We price every job individually. The things that drive the figure:
- The site’s rules and procedures
- Backing rod, priming and other preparation
- Location, for remote and island sites
- Specialist products, such as fire-rated or hygienic sealants
Quantities, awkward access and phased working all shape the price. So do site requirements such as inductions and permits, along with the time of year for external work.
Details that help us quote
To price the job accurately, we need to understand the site. Useful things to include:
- How the joints are reached, and at what height
- Rough lengths or quantities, or drawings if you have them
- What the building is and how it’s used
- Whether an asbestos survey exists
Send us photographs, drawings or a joint schedule and a fixed quote comes back to you. If the job needs a look first, we will arrange a site visit.

Questions we’re asked in Sedrup
Do you cover business parks and estates near Sedrup, such as Fountain Business Centre?
Yes, sites like Fountain Business Centre are within our area, along with the rest of Sedrup. Send details of the unit and the work through our quote form for a quick quote.
Do you work for managing agents with blocks near Aylesbury station?
Yes, and several blocks can go on one quote. We work to your notice and access arrangements.
Do you work to architects’ specifications?
Yes. Send it with your enquiry, and the quote will be based on it.
How long before the joints can be used?
The product and site conditions decide that. Some take light use quickly, others need longer to cure, so we will confirm the curing time on the day.
How long does a job like this take?
That varies with the scale of the job, though a typical visit normally takes one or more days per building, depending on the joint lengths and the access. Larger or phased jobs take longer, and we will give you a timescale with the quote.
Who decides which product is used?
The specification comes first, if there is one. Without one, the joint decides: how much it moves, what it bonds to and whether it’s wet, trafficked or fire-rated.
Does weather matter for sealant work?
Outside, yes. Sealant needs a dry joint and a temperature within the product’s range, so frost, rain or cold mornings can delay outside work. Internal work is rarely affected.
Surface by surface
Commercial and mixed-use buildings
Commercial buildings have mastic at shopfronts, entrances and external joints. We work across portfolios on a planned basis.
Window and door perimeters on blocks
Perimeter joints on blocks are best done elevation by elevation or block by block. Access is agreed with you before the quote is fixed.
What we can’t put right
Not every problem is a sealant problem, and we’d rather tell you before you spend money. It won’t fix:
- Water coming in from the roof or rainwater goods
- Masonry that has broken away beside the joint
- Broken glass or failed sealed units
If you’re not sure, just call 01277 525 020 or send details through our quote form and we will give you a straight answer before you book.
What we seal
- Communal entrances and stairwells
- Balcony and threshold joints
- Communal kitchens and washrooms
- External wall and movement joints
- Window and door perimeters on blocks
- Shopfronts below residential blocks
Planned mastic for Sedrup portfolios
Sedrup is about 38 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. Rainfall across the South East, Sedrup included, is lower than in many parts of the UK. Outside mastic still needs a dry joint and the right temperature, and the sunniest, most exposed sides of a building typically need attention first.
Student blocks close to universities like University Campus Aylesbury Vale, 1.9 miles north-east of Sedrup, are easiest to work on between tenancies. Buildings close to stations like Aylesbury station, 1.7 miles north-east of Sedrup, are often flats over shops, with frame mastic to keep sound. For a school such as Stone Church of England Combined School, perimeter mastic on windows and doors is a holiday job.
Sedrup is about 2 miles south-west of Aylesbury, in Buckinghamshire. Any commercial site in Sedrup is covered. Sedrup is one of 308 places in Buckinghamshire on our list for mastic joints. Our Oxford page has more on work in that area.

Diagnose, treat, sign off
Where the site stays busy, the work is phased so only one area is out of use at a time. Each section is protected, cleaned back and sealed, then reopened once the sealant allows before we move to the next. Smaller jobs around Sedrup can be grouped with others nearby, which keeps travel down. A fixed quote is given before anything starts.
- First comes a look at the joints and, for older buildings, the asbestos records.
- The products and programme are set out in a fixed quote.
- Failed mastic is removed completely.

Preparing the site

Site staff or a sealant specialist?
Using site staff can make sense for a small touch-up, but larger jobs are different: a specialist brings efficiency, a consistent finish and a 12-month guarantee.
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.
Aftercare for building managers
A few simple habits keep the new joints working:
- List the paperwork your organisation requires when you send details
- Make it easy for occupiers to report draughts
- Make mastic part of routine maintenance checks
- Reduce knocks to communal area joints
Protect entrance and corridor joints from knocks where possible. Knocks cause many early failures in communal areas.
Water getting in round frames can damage plaster, decoration and the frames themselves. Early resealing is far simpler than repairs inside.
