How we handle facade sealing in Coombe
Managing agents and owners in Coombe ask us to, we reseal perimeters across whole elevations or a handful of problem windows. Either way, the method is the same: old sealant out, faces cleaned, depth set and a new bead tooled in. A 12-month guarantee applies to our workmanship. Most enquiries involve cold air coming in at window perimeters and weathered facade joints that have lost their grip, across window and door perimeters, cladding panel joints and coping and flashing joints. For commercial sealant work in Coombe, you deal with one contact from quote to sign-off, for single jobs and planned programmes alike.
Around smaller places like Coombe, building work normally means conversions of farm buildings, a few new houses or an extension to a hall or school. Each still needs a proper mastic package: window perimeters, facade joints and internal sealant to the specification.
We stand behind the joints we seal: 12 months, guaranteed. That covers our preparation and application.

After the work
Problems stay small when the joints are checked regularly. In particular:
- Investigate damp beside windows promptly
- Keep sills, gutters and drainage paths clear
- Combine resealing with other works that need access
- Brief window cleaners about newly sealed joints
Let the new sealant cure before washing the facade or windows near it. Pressure washers and harsh cleaners can damage a fresh bead, so brief your window cleaners.
Use each reseal to correct the joint: correct depth, proper backing and a sealant that can take the movement. Repeating a faulty detail just repeats the failure.
New build and refits around Coombe
At about 34 miles from central London, Coombe is within reach of the capital. Construction around the commuter belt mixes station-side flats with refurbished offices and units, so mastic packages have to keep pace with busy programmes. Coombe has several hotels close by, all within 2 miles. Hotel refurbishments often run to tight programmes between busy periods, and perimeter and sanitary sealant has to keep up.
Hospital estates such as The Paddocks Hospital (2.5 miles south-west of Coombe) tend to grow and change in phases, often next to occupied wards, so facade and perimeter sealing has to fit the estates team’s plan. Units on estates such as Station Approach Business Park, 1.5 miles to the north-east of Coombe, tend to be reclad and refitted as tenants change, and each job leaves cladding and perimeter joints to seal.
Coombe is about 5 miles south of Aylesbury, in Buckinghamshire. Businesses, contractors and managing agents in Coombe can call on us for facade joints, as part of our coverage of Buckinghamshire.

What affects the price in Coombe
Your fixed quote is built from the real scope. It allows for:
- Access and working height
- The size and state of each joint
- Whether the work must be split into stages
- Removal of failed or old sealant
Every site prices differently: the joint sizes, the specified product, access and working hours each have a bearing. A fixed quote follows once we understand the job.
Details that help us quote
A few photographs plus some basic facts will normally do. Please tell us:
- Asbestos survey details if the building is older
- Photos of the joints, close up and from further back
- Approximate linear metres or a joint schedule
- Any specification or named product
Every quote starts with the facts: what’s there, how much of it, how we reach it and what’s specified. Send what you have, and we’ll arrange a site visit if anything is unclear.
Common questions from Coombe clients
Can you work at a site such as Station Approach Business Park, by Coombe?
Yes. Estates, retail parks and business parks around Coombe, Station Approach Business Park among them, are all within reach. A few photographs and the unit address let us price the work.
Is Coombe off your patch?
Not at all: smaller places are covered as well as towns. We work across Greater London and the South East. Send photos and a list of what needs doing, and we’ll plan the job to need as few trips as possible.
Can one quote cover more than one building?
Yes. We take on portfolio and planned maintenance work, with each site phased to suit its occupants.
Do your applicators hold CSCS cards?
Yes. Our applicators hold CSCS cards.
What type of sealant goes on window perimeters?
Most facade and window perimeter joints take a low-modulus neutral-cure silicone. Hybrid or MS polymer, polyurethane and polysulphide sealants suit others, depending on the substrate and the specification.
Can you follow the specification on our project?
Yes. Include it with the drawings when you ask for a quote, and the quote will be based on it.
How much does the work cost?
That depends on the job: quantities, access, the product and any phasing. Call for a fixed quote and we’ll price it properly.
On site: what to expect
A typical day starts with protection: masking tape along the joint edges and sheeting over anything nearby. On site, the work usually takes a day or two for a few elevations, and longer where access has to be moved around the building, and our waste is bagged and taken away as we go. Rural sites near Coombe may need directions, gate codes or a contact on site. Add it to your enquiry and we will build it into the plan.
- First we review photographs, drawings or what we saw on a visit, and agree how each joint will be reached.
- Failed sealant is cut out along its full length.
- 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
- For older buildings, check the asbestos register before work
- Tell us which areas need to stay in use
- Explain the parking and delivery arrangements

How the job changes by surface
Cladding panel joints
On sealed panel systems, every joint keeps water out. Failed runs are cut out and rebuilt end to end to the correct depth.
Render and coated surfaces
Sealant can only hold as well as the render or paint beneath it. We remove flaking material so the bead bonds to a firm surface, and areas needing repair are flagged.
Common problems we fix in Coombe
Adhesive failure, where the sealant peels away from one face, normally comes from poor preparation. Contamination, moisture or skipping the primer the maker specifies leave a weak bond, and the joint opens with the first real movement.
Typical triggers for a call:
- Staining on stone next to old sealant
- Failed sealant on precast panel joints
- Leaks at window and door perimeters
- Sealant pulling away from frames or panels
Projects at schools like Great Kimble Church of England School work to term dates, so mastic is programmed tightly.
What your quote should include
- How joint depth will be controlled
- Will CSCS-carded applicators be on site?
- The terms of the workmanship guarantee
- Will RAMS and insurance details be available?
