Questions about Waltham
Can you work to our programme on a site in or near Waltham?
Yes. Send the programme and drawings, and we’ll plan the mastic to suit the stages. Any paperwork you need, from RAMS to our insurance certificate and CSCS details, is confirmed with the quote.
Do you take on work at healthcare sites like Kent and Canterbury Hospital?
Yes. Healthcare sites are among the places we work. Each area is agreed with the ward or department and the estates team in advance.
Do we need an asbestos check before resealing?
For older buildings, yes, check before work starts. The dutyholder holds the asbestos register. If asbestos is suspected, work stops until it is tested.
How long does a job like this take?
That varies with the scale of the job, but the work typically takes anything from a single day to several weeks, depending on joint lengths, access and the weather. For bigger or phased jobs, we will set out a timescale with the quote.
Do you take on small jobs?
We quote for single jobs as well as large packages and programmes. Photos and a description are enough to start.
Which sealant will you use?
A specification, where there is one, decides it. If there isn’t one, it comes down to the joint: how much it moves, what it bonds to and whether it’s wet, trafficked or fire-rated.
Is the work guaranteed?
Yes. Our workmanship is backed for 12 months on every job.
Facade sealing for commercial buildings in Waltham
Managing agents and owners in Waltham ask us to, we reseal perimeters across whole elevations or a handful of problem windows. The approach doesn’t change with the size: cut out, clean, back, prime where needed and seal. A 12-month guarantee applies to our workmanship. We work on window and door perimeters, stone and brick facade joints and shopfront frames, and the usual reasons a site gets in touch are cladding panel joints that have opened up and leaks at window and door perimeters. A specialist sealant contractor works differently from a general builder: on jobs in Waltham, preparation and product choice get the time they need.
Sites around smaller places like Waltham can be a fair drive from suppliers, so we come with everything the package needs, timed to the stage the job has reached. Send drawings or photographs and the programme and we’ll quote to suit.
We stand by our work: 12 months, guaranteed. It covers how we prepared and applied the sealant, and if something we did falls short, we return to it.

Our process
We begin with a short walk round with whoever looks after the building, 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. Smaller jobs around Waltham can be grouped with others nearby, which keeps travel down. You will have a fixed quote before work starts.
- We plan access and the order of elevations with the client.
- We only seal when joints are dry and within the product’s temperature range.
- Each joint is cut out and the edges inspected.
- Faces are cleaned, primed where needed and backed.
- Facade-grade sealant goes in and is tooled to a tidy concave profile.
- We hand over with our 12-month workmanship guarantee.
Before we start on site
- Send your site hours and access windows
- Explain the parking and delivery arrangements
- Point out any areas we must not close

Specifications, drawings and tender packages are welcome with any enquiry, and we will price the work to it. Smaller jobs need nothing more than photos and a few notes.
Advice
Leave it or put it right?
The longer a failed joint is left, the more the substrate suffers: edges get wet, render and timber deteriorate and frames can move. Early action keeps it simple. Older rural buildings around Waltham move with the seasons, and rigid or tired sealant can’t keep up. A sealant with the right movement capability, correctly sized, lasts far better.
Every site prices differently: joint size, product, access and site hours all play a part. A fixed quote follows once we understand the job.

Signs you need facade sealing in Waltham
Cohesive failure, a split through the middle of the bead, points to an over-stretched joint. Too thin a bead, too narrow a joint or a product with the wrong movement class are common reasons.
Typical triggers for a call:
- Discoloured or dirty facade joints
- Sealant pulling away from frames or panels
- Hard, chalky sealant that no longer flexes
- Cold air coming in at window perimeters
Sites around Waltham get mastic sealed to the drawings and the programme, nothing improvised.
Before you book anyone
- Proof of insurance
- Their pre-qualification and accreditations
- Will RAMS and insurance details be available?
- Will failed sealant be removed rather than covered?
When it isn’t the sealant
Honesty saves time and money. Fresh joints won’t solve:
- Replacing glass or failed glazing units
- Joints whose design needs changing by the specifier
- Water getting in through cracked render or porous masonry
If in doubt, ring 01277 525 020 or send photos by email and we will say what we think before you book.

New build and refits around Waltham
Waltham lies roughly 52 miles out from central London. Commuter-belt towns tend to see a steady flow of new flats, offices and commercial schemes, and each scheme needs its mastic sealed to programme. Waltham is in the South East, one of the UK’s drier regions. Winter mornings still bring frost and condensation on frames and panels, so the external programme keeps a little slack.
For a contractor working at a hospital such as Kent and Canterbury Hospital, 5.5 miles to the north-east of Waltham, perimeter and facade sealing is planned around patients and deliveries.
Waltham is about 6 miles south-west of Canterbury, in Kent. We cover commercial sites throughout Waltham. We work across 931 places in Kent, large and small. Our London page has more on work in that area, about 52 miles away.
We take on facade joints across the CT4 postcode area. For a building on Church Lane, Richdore Road and Kake Street or nearby, send details and we’ll quote for facade joints. Close to Waltham, our area also takes in Stelling Minnis (2 miles east), Bossingham (2 miles east), Stowting Common (4 miles south), Stowting (4 miles south) and Rhodes Minnis (4 miles south-east). Bigger towns within reach include Ashford (8 miles south-west), Canterbury (6 miles north-east), Dover (13 miles east), Folkestone (10 miles south-east), Whitstable (11 miles north) and Faversham (10 miles north-west).
What’s near Waltham
Locally, jobs take us to sites close to Compasses Inn, among other places. The closest station to Waltham is Chilham station, roughly 3.7 miles north-west of the centre. Nearby you will also find Chilham Castle (4.1 miles north-west) and Kent and Canterbury Hospital (5.5 miles north-east).
Looking after the joints
Cleaning and maintenance staff play a part too. Pass these on to them:
- Avoid harsh cleaners on facade sealant
- Never let anyone seal over old sealant
- Share access with other external trades
- Report water ingress at frames as soon as it shows
Keep gutters, sills and drainage paths clear. Sealant copes better when water runs off the facade as designed instead of soaking the joints.
In pre-2000 buildings, check the asbestos register before old sealant is cut out. Some older mastics contain it, and work stops until it’s tested if it’s suspected.
