Facade sealing in Cheapside, done properly
We seal window and door perimeters, cladding panel joints, external facade joints and perimeter joints where frames meet the structure for clients around Cheapside. Coping and flashing joints are included where sealant is the specified fix. We work on stone and brick facade joints, window and door perimeters and perimeter joints where frames meet the structure, and the usual reasons a site gets in touch are old perimeter mastic that has dried out and perimeter sealant that has split or peeled away. Whether you call it commercial sealant work, mastic application or joint sealing, in Cheapside it comes down to the same thing: failed joints cut out, faces prepared and the right sealant laid to the right depth.
Construction in and around smaller places such as Cheapside 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.
Every job we finish is backed by a 12-month workmanship guarantee, in Cheapside as everywhere else we work. If our installation lets you down in that time, we return and fix it.

What we are called out for in Cheapside
Most facade joints fail through age and weathering. The bead hardens, chalks on the surface and loses the flexibility to follow the joint, then it splits or peels.
Any of the following is a good reason to get the joints checked over:
- Water coming in around window frames
- Perimeter sealant that has split or peeled away
- Cladding panel joints that have opened up
- Hard, chalky sealant that no longer flexes
On a campus such as Imperial College Silwood Park Campus (0.5 miles south of Cheapside), new teaching buildings and residences are normally built and refurbished around the academic year.

What else we do in Cheapside
Cost factors for facade joints
A fixed quote reflects the actual work. It allows for:
- Site requirements such as inductions and permits
- How much there is to seal
- Specialist products, such as fire-rated or hygienic sealants
- Any access equipment needed
Quantities, awkward access and phased working all shape the price. So do site requirements such as inductions and permits, along with the time of year for external work.
What to include in your enquiry
It doesn’t need to be a full survey. A few details are enough to get going:
- Any specification or named product
- The type of building and who uses it
- A wide shot and a close-up of the area
- Whether an asbestos survey exists
A handful of photos and a postcode is the fastest way to a quote. Upload them with the quote form, or ring 01277 525 020 or use the quote form if you’d rather talk the job through.
Honest limits
A proper diagnosis includes knowing what sealant can’t do. We will tell you if the real problem is one of these:
- Damp caused by condensation inside the building
- Cracked or spalling substrates that need repair before sealing
- Specialist high-level access methods
If you are not sure, just phone 01277 525 020 or email the details over and we will give you a straight answer.

How a job runs
The first thing on site is a walk round with your contact, agreeing which joints are in scope, where to start and what must stay open. Then we strip out anything that has failed, prepare every joint and seal it. If others near Cheapside need work, visits can be combined, which keeps travel down. A fixed quote is given before anything starts.
- We look at the joints, the drawings and the access before pricing.
- Failed sealant is cut out along its full length.
- Both faces are cleaned and, where the product needs it, primed.
- 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
- Flag any permit to work we will need
- Agree which areas must stay open
- Clear stock, furniture or equipment away from the joints

Different surfaces, different methods
Render and coated surfaces
Rendered and painted facades need a sound edge for the sealant to bond to. Loose coatings are cleaned back first, and we will mention any edges that need repair.
Cladding panel joints
Joints between cladding panels open and close with temperature. The sealant has to match the movement and the panel finish, as the specification sets out.
Facades, frames and programmes in Cheapside
Cheapside sits in one of the drier corners of the country, the South East. Winter mornings still bring frost and condensation on frames and panels, which is why external dates are agreed with the site manager. At about 24 miles from central London, Cheapside is within reach of the capital. 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.
For a contractor working at a hospital such as Heatherwood Hospital, which lies south-west of Cheapside, perimeter and facade sealing is planned around patients and deliveries. Recladding or extending a unit at a site like Ascot Business Park (1.6 miles south-west of Cheapside) brings panel joints and frame perimeters into the programme.
Cheapside is about 4 miles south of Windsor, in Windsor and Maidenhead. Cheapside sits inside our coverage, with the same fixed quotes and 12-month guarantee as everywhere else. 60 places across Windsor and Maidenhead fall within our area, including Cheapside.

Questions we’re asked in Cheapside
Will you plan work around the academic year at somewhere like Imperial College Silwood Park Campus?
Yes, holiday working periods are the norm on campus jobs. Let us know which documents your site asks for, and we’ll confirm them alongside the quote.
Is a smaller place like Cheapside outside your area?
No. Places such as Cheapside are covered as much as the big towns. Our area covers London and the South East counties. We plan jobs in smaller places so return trips are kept to a minimum.
Can you just add new sealant on top?
No. New sealant won’t hold on old sealant, so the old bead is cut away. Nothing else gives a bond that lasts.
Are you insured?
Yes. Mastic Doctor is fully insured, public liability included.
Do you hold CHAS accreditation?
Yes. Mastic Doctor is CHAS accredited and a Constructionline member.
Is any job too small?
Small jobs are welcome alongside larger packages. Photos and a description are enough to start.
Can you handle several sites?
Yes. We take on portfolio and planned maintenance work, planned site by site to suit how each building is used.
