About our facade sealing in Walton
External sealing depends on the weather more than most trades. The sealant needs a dry joint and temperatures inside the maker’s limits, so frosty or damp mornings can hold work back. We build that into the programme and tell you if the forecast changes the plan. Site teams most often ask us about cladding panel joints that have opened up and damp patches beside frames after rain, on shopfront frames, stone and brick facade joints and cladding panel joints. Most enquiries from Walton start with one failed joint and grow into a wider look at the building: we check the joints around it and give you an honest view of what needs doing now and what can wait.
Construction in and around smaller places such as Walton is often barn conversions, small groups of houses or extensions to halls and schools. Each still needs a proper mastic package: window perimeters, facade joints and internal sealant to the specification.
The 12-month guarantee covers our workmanship: preparation, application and finish. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

Contractors’ notes for Walton
Walton is about 37 miles from central London. Commuter-belt towns tend to see a steady flow of new flats, offices and commercial schemes, and main contractors there need mastic that keeps to the programme. A number of hotels sit less than 2 miles from Walton. When hotels extend or refit, the work is typically squeezed between peak periods, mastic included.
Projects at colleges like Buckinghamshire College Group, 0.7 miles to the west of Walton, tend to run to term dates, so the mastic is planned tightly. University estates such as University Campus Aylesbury Vale, under half a mile to the north-west of Walton, tend to have a rolling programme of new buildings and refurbishments, each with window perimeters and facade joints to seal. When units on a site such as Vale Retail Park (to the north of Walton) are refurbished or reclad, the panel joints and window perimeters are part of the mastic package.

Our process
The first thing on site is a walk round with your contact, to confirm the scope, the order of work and any areas we must keep clear. After that, any old or failed material is removed, each joint is prepared and the new sealant goes in. For work around Walton, we aim to finish in one visit, so photographs and measurements up front really help. Then the right materials arrive with us.
- We look at the joints, the drawings and the access before pricing.
- The old bead is cut away completely, not overlaid.
- Joint faces are cleaned to firm, sound material, with primer where the sealant maker specifies it.
- Closed-cell rod fixes the depth, and the sealant grips two sides only.
- The new sealant goes in and is tooled firmly onto both faces.
- The completed runs are checked with you, then the 12-month guarantee applies.
What we need from you
- Tell staff and tenants when we will be in
- Send your site hours and access windows
- Point out any areas we must not close

Related advice
When it isn’t the sealant
A proper diagnosis includes knowing what sealant can’t do. We’ll tell you if the real problem is any of the following:
- Specialist high-level access methods
- Damp caused by condensation inside the building
- Work on the window or framing system itself
If you are not sure, just phone 01277 525 020 or send photos by email and we’ll give you a straight answer.
What we seal
- Cladding panel joints
- Coping and flashing joints
- Window and door perimeters
- Perimeter joints where frames meet the structure
- Stone and brick facade joints
- Shopfront frames
What happens if it’s left?
If access is already up for other work, resealing at the same time makes sense. Coordinating facade sealing with other external works avoids paying for access twice, saving a second set-up. Around Walton, it’s better to renew all the failing joints at once, rather than one at a time. Send photographs of each area and we will quote for the lot.
No two sites price the same: the joint sizes, the specified product, access and working hours each have a bearing. A fixed quote follows once we understand the job.

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.
Certain joints really need a specialist: for example fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. A poor seal in places like these tends to cost more to put right later.
Common questions from Walton clients
Is Walton too far out for you?
Not at all: smaller places are covered as well as towns. We cover Greater London and the counties of the South East. We plan jobs in smaller places so return trips are kept to a minimum.
Is hospital work, at somewhere like Royal Buckinghamshire Hospital, something you do?
Yes, provided the work is planned with the site’s estates team. Each area is agreed with the ward or department and the estates team in advance.
Do you replace windows or glass?
No. Glazing, windows and glass replacement aren’t part of our work. We seal the joints around them, including perimeters where frames meet the structure.
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.
Is it fine to apply new sealant on top of old?
No. We cut the old material out and clean the joint back before sealing, since fresh sealant will not bond reliably to aged material.
What type of sealant goes on window perimeters?
It depends on the joint, the substrate and any specification. BS EN 15651 Parts 1 and 2 cover facade and glazing sealants, and specifications often name them, and we work to what is specified.
How much does the work cost?
There isn’t a price list, as every site differs. With photographs or drawings, we can give you a fixed quote.

Surface by surface
Brick and stone facades
Brick and stone facades have perimeter and movement joints that need a compatible sealant. Neutral-cure products are used because acetoxy types can mark some stone, and primers go on where specified.
Cladding panel joints
Panel joints on cladding and rainscreen systems take movement every day. The sealant has to match the movement and the panel finish, as the specification sets out.
