Keeping the joints sound
For the best life from the joints:
- Check that rainwater leaves the facade the way it was designed to
- Add perimeter sealant to planned maintenance checks
- Insist on a full cut-out when joints are renewed
- Ask about asbestos in pre-2000 mastic
Look at perimeter and panel joints as part of routine building checks. Signs to look for are cracking, edges lifting, chalking and stiffness; note where they appear.
Check older buildings for asbestos before disturbing old mastic. Some older mastics contain it, and if it’s suspected, we stop until it has been tested.
Facade sealing for commercial buildings in Tongham
Every facade quote starts with how the joints will be reached. Let us know what access exists or is planned, and any site rules we need to work around, and we’ll fit the work around it. Most enquiries involve new sealant peeling off old mastic and discoloured or dirty facade joints, across perimeter joints where frames meet the structure, stone and brick facade joints and window and door perimeters. Whoever orders the work in Tongham, the brief is usually the same: a clear scope, tidy work and joints that don’t fail again.
Around places like Tongham, a lot of construction is the conversion of older buildings, which leaves joints between old walls and new frames that need a sealant able to take the movement.
Every job is signed off with a 12-month guarantee. The promise is simple: if our work fails within that year, we put it right.

General trades versus a specialist
Certain joints really need a specialist: for instance 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.
Using site staff can make sense for a small touch-up, but anything bigger is another matter: a specialist brings efficiency, a consistent finish and a 12-month guarantee.
Why act early in Tongham
Leaving failed perimeter sealant also makes the eventual job bigger: wet edges break down, so repairs may be needed before resealing. Acting at the first sign of splitting keeps the fix simple. A failed joint lets water into a building whatever its size. Early resealing avoids the damage that follows a leak.
Quantities, awkward access and phased working all shape the price. Site requirements like inductions and permits play a part as well, along with the time of year for external work.

How a job runs
Occupied buildings need a little choreography. We sign and contain the area we are in, keep walkways clear and move on in phases so staff and visitors can carry on around us. For a job in Tongham, the main thing is a clear picture of the work, so send photographs of each area. You will then get a fixed price for the work.
- We look at the joints, the drawings and the access before pricing.
- 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.
- Backing rod, or bond-breaker tape in shallow joints, limits the depth.
- The new sealant goes in and is tooled firmly onto both faces.
- We walk the finished joints with you before handing over.
Before we start on site
- Point out any areas we must not close
- Send your site hours and access windows
- Move anything stored against the joints

Common problems we fix in Tongham
Overlaying old sealant is a common shortcut that fails quickly. Cured silicone won’t accept a new silicone bead, and the patch soon lifts.
What tends to prompt an enquiry:
- Discoloured or dirty facade joints
- Air leaks through failed facade joints
- Hard, chalky sealant that no longer flexes
- New sealant peeling off old mastic
New wings at hospitals like Farnham Community Hospital (2.4 miles west of Tongham) bring long runs of window and panel joints to seal.

Common questions from Tongham clients
Is Tongham too small for you to travel to?
No. Places such as Tongham are covered as much as the big towns. We work across Greater London and the South East. Good photos up front let us bring everything on the first visit.
Do you take on work at healthcare sites like Farnham Community Hospital?
Yes, hospitals are one of the sectors we cover. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.
Do you offer coloured sealant?
Often, yes. Sealants are made in a wide range of standard colours, and matching to RAL references or nearby finishes is commonly requested. We confirm what’s available for the specified product when we quote.
Will you come and look before quoting?
Photos, drawings or a schedule are often enough to quote. Where they aren’t, we arrange a site visit.
Does the weather affect the work?
Outside, yes. The joint has to be dry and within the product’s temperature range, so damp, frosty or very cold days can stop external work. Inside work is seldom held up.
Are you CHAS accredited and on Constructionline?
Yes. Mastic Doctor is CHAS accredited and a Constructionline member.
Do you guarantee your work?
Yes. The 12-month guarantee covers our preparation and application, but not damage, misuse or other trades’ work.
Facade sealing around Tongham: how the place shapes the job
Tongham is in the South East, one of the UK’s drier regions. Winter mornings still bring frost and condensation on frames and panels, which is why external dates are agreed with the site manager. Tongham lies roughly 33 miles out from central London. Building activity in the commuter belt runs from new flats near stations to business park refurbishments, so mastic packages have to keep pace with busy programmes.
When a college such as Aldershot College (0.8 miles north of Tongham) builds or refurbishes, the mastic package normally has to fit around students and staff. Work at a hotel such as Hog's Back Hotel (to the south-east of Tongham) tends to be programmed around bookings, mastic included.
Tongham is about 1 mile south-east of Aldershot, in Surrey. We cover commercial sites throughout Tongham, for single jobs and planned programmes alike. Our Surrey coverage takes in 379 places, from busy centres to rural villages. Sites around Reading have their own page, roughly 18 miles from Tongham.
Commercial sites across GU10 are covered for facade joints. Streets here include The Street, Chester Way and Lambourne Way. We also cover Sandy Cross (1 mile south), Ash (1 mile north-east), Seale (1 mile south-east), Ash Green (1 mile north-east) and Badshot Lea (1 mile west) for facade joints. Bigger towns within reach include Guildford (7 miles east), Woking (9 miles north-east), Camberley (7 miles north), Farnham (3 miles south-west), Frimley (6 miles north) and Haslemere (10 miles south).
Landmarks near Tongham
We work on buildings around Aldershot Park, The White Hart pub and Ash Manor School and the streets around them. Tongham’s nearest station is Ash station, about 1.4 miles north-east of the centre. A little further out are Farnham Castle (3.2 miles west) and Guildford Hospital (5.3 miles east). Green spaces nearby include Aunt's Pool and Hog's Back.
What sealant work can’t fix
Honesty saves time and money. New sealant won’t cure:
- Cracked or spalling substrates that need repair before sealing
- Joints too narrow for the movement they take, which need redesign
- Installing or repairing glazing systems
