Facade sealing in Great Horwood, done properly
Facade sealants sit in the sun, rain and frost every day, so they don’t last indefinitely. How long a joint lasts depends on the movement it takes, its exposure, the product and how well it was installed. When the time comes, we cut the old sealant out completely and start again. We work on shopfront frames, window and door perimeters and cladding panel joints, and what we’re called in for most is previous reseals run over old sealant and perimeter sealant that has split or peeled away. Facilities teams, main contractors and managing agents in Great Horwood tend to want the same three things: a clear scope, tidy work and joints that don’t fail again.
Construction in and around smaller places such as Great Horwood is often barn conversions, small groups of houses or extensions to halls and schools. Perimeters, facade joints and internal sealant all need doing properly, however small the scheme.
The 12-month guarantee covers our workmanship: the preparation, the sealing and the tooling. It doesn’t extend to damage, other trades’ later work or movement the joint was never designed to take.

Mastic packages on Great Horwood sites
Great Horwood lies roughly 47 miles out from central London. Towns within reach of London tend to keep building, from flats to offices and schools, so mastic packages have to keep pace with busy programmes. Great Horwood sits in one of the drier corners of the country, the South East. Still, external mastic needs dry faces within the maker’s temperature limits, which isn’t every day, so external mastic is timed for workable conditions and agreed with the site manager.
New units and refits on sites such as Greenway Business Park (0.5 miles south of Great Horwood) need their panel and perimeter joints sealed to the specification. Building work at universities like University of Buckingham, 4.6 miles west of Great Horwood, is often timed for the summer, mastic included. With historic properties like Claydon House, 4.9 miles south-west of Great Horwood, in the area, refurbishment work often meets old masonry that needs compatible sealants.
Great Horwood is about 5 miles east of Buckingham, in Buckinghamshire. Businesses, contractors and managing agents in Great Horwood use us for work on facade joints. Our Buckinghamshire coverage takes in 308 places. Sites around Oxford have their own page, about 22 miles away.

Quoting for work in Great Horwood
Sealant work doesn’t have a standard rate, because every site is different. What we look at:
- Induction, permit and paperwork requirements
- How much there is to seal
- Specialist products, such as fire-rated or hygienic sealants
- Access and working height
Access can matter as much as the joints themselves: easy-to-reach joints are quicker than those that need equipment to get to. Mention the access as part of your enquiry.
What to include in your enquiry
However big the job, the same details help:
- The site address and postcode
- Photos of the joints, close up and from further back
- How the joints are reached, and at what height
- The type of building and who uses it
If there’s a specification, drawings or a tender package, send it with your enquiry, and we will price against exactly what is specified. For smaller jobs, photographs and a description will do.
What sealant work can’t fix
Not every problem is a sealant problem, and we’d rather tell you before you spend money. It won’t fix:
- Joints too narrow for the movement they take, which need redesign
- Cracked or spalling substrates that need repair before sealing
- Work on the window or framing system itself
If you’re not sure, just call 01277 525 020 or send photos by email and we’ll give you a straight answer before you book.
What we seal
- Coping and flashing joints
- Stone and brick facade joints
- Cladding panel joints
- Window and door perimeters
- Perimeter joints where frames meet the structure
- Shopfront frames
Why deal with it now?
A few metres of new sealant compare well with replacing ceilings, linings or damaged stock. Water through a failed joint rarely stays where it starts, so the real damage is often some distance away. Converted and older buildings near places like Great Horwood tend to move, and aged sealant cracks. The right product, sized to the joint, copes much better.
No two sites price the same: the joint sizes, the specified product, access and working hours each have a bearing. Send the details and a fixed figure follows.

FAQs: Great Horwood
Can work at a site such as University of Buckingham fit around teaching?
Yes, holiday working periods are the norm on campus jobs. Any paperwork you need, from RAMS to our insurance certificate and CSCS details, is confirmed with the quote.
Does your area include sites such as Greenway Business Park, near Great Horwood?
Yes. We cover Great Horwood and the area around it, including industrial estates, business parks and retail parks such as Greenway Business Park. To start, just call 01277 525 020 or email us with the unit, the joints involved and your access times.
Do you guarantee your work?
Yes, for 12 months. If a joint fails because of how we installed it, we come back and put it right.
Do you install glazing systems?
No. We don’t install glazing systems, windows or glass. We seal the joints around them, including perimeters where frames meet the structure.
Should we check old sealant for asbestos?
Some older mastics, especially in pre-2000 buildings, can contain asbestos. The dutyholder’s asbestos register should be checked first, and if anything is suspected, we stop until it’s tested. Removal of asbestos isn’t something we do.
Can staff carry on working while you’re here?
Yes, with some planning. Tell us your site hours and access windows and we’ll plan around them.
Who decides which product is used?
A specification, where there is one, decides it. Without one, the joint decides: how much it moves, what it bonds to and whether it’s wet, trafficked or fire-rated.

How the job changes by surface
Window and door perimeters
Frame materials vary, and so does the preparation. We clean and prime to the sealant maker’s guidance for each surface.
Cladding panel joints
Where panels are sealed rather than open-jointed, the bead is part of the weather line. Failed runs are cut out and rebuilt end to end.
