Facade sealing in Crockham Hill
External joints face UV, rain, temperature swings and building movement all year, and they wear out over time. How long a joint lasts depends on the movement it takes, its exposure, the product and how well it was installed. When it fails, the whole bead is cut away and the joint rebuilt. If you are dealing with hard, chalky sealant that no longer flexes and facade joints cracked through the middle, we can put it right, whatever the surface. A single leaking joint is often how a building in Crockham Hill first comes to us: we look at the rest while we are there and tell you what we find.
Around smaller places like Crockham Hill, building work usually 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.
Building owners and contractors get the same cover: a 12-month guarantee on our workmanship. Faults in the structure, damage and other trades’ work fall outside it, and we say so plainly.

How the job changes by surface
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.
Perimeter joints at frames and structure
Perimeter joints at frames often show their age first. We cut them out, prepare both faces and reseal to the specification using a sealant classified for that use.
When to bring in a specialist
Some joints are best left to specialists: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. Getting these wrong normally costs more in the end than doing them right.
What you see is the finished bead, but most of the work is hidden. Backing rod, primer where specified and a joint designed to move with the building are easy to get wrong without experience.
Quoting for work in Crockham Hill
The price varies from site to site. Expect it to depend on:
- Removal of failed or old sealant
- How much there is to seal
- Whether the work must be split into stages
- Site requirements such as inductions and permits
Whether it’s a single area or a whole estate, the same things set the price: what’s in scope, how we reach it, what’s specified and when it needs doing. Call for a quote and we will put a fixed figure on it.
Before you send an enquiry
For an accurate fixed quote, we need a clear picture of the site. Send us:

- Approximate linear metres or a joint schedule
- Any dates the work must fit around
To get a fixed quote, call the office on 01277 525 020 or email a schedule or drawings, telling us the site location and the nature of the job. You can also send details through our quote form.
Facade sealing around Crockham Hill: points for this area
At about 19 miles from central London, Crockham Hill is within reach of the capital. Building activity in the commuter belt runs from new flats near stations to business park refurbishments, which keeps mastic packages in demand. Rainfall across the South East, Crockham Hill included, is lower than in many parts of the UK. Winter mornings still bring frost and condensation on frames and panels, which is why external dates are agreed with the site manager.
Older buildings in the area around Crockham Hill, such as Chartwell, 1 mile north-east of Crockham Hill, need care when sealed: the product has to suit soft or historic materials. New wings at hospitals like Tandridge Priory (2 miles north-west of Crockham Hill) bring long runs of window and panel joints to seal.

Crockham Hill: questions and answers
Is Crockham Hill too small for you to travel to?
No. Small places get the same service as large ones. We work across Greater London and the South East. We plan jobs in smaller places so return trips are kept to a minimum.
Can you work on a hospital site such as Tandridge Priory?
Yes, healthcare and care buildings are part of our work. The estates team’s permit system and infection-control rules come first, and the work is planned around them.
How long before the joints can be used?
That comes down to the sealant and the temperature. Some take light use quickly, others need longer to cure, and we confirm it before leaving site.
Can one quote cover more than one building?
Yes. We take on portfolio and planned maintenance work, planned site by site to suit how each building is used.
Do you hold CHAS accreditation?
Yes. Mastic Doctor is CHAS accredited and a Constructionline member, which helps with supplier vetting.
Do you replace windows or glass?
No. A glazing contractor handles that. What we seal are the joints around frames and panels across the facade.
Are you insured?
Yes. Mastic Doctor is fully insured, public liability included.

Honest limits
Our job is the joint, not everything around it. On its own, sealant can’t deal with:
- Render or concrete edges that have broken away
- Arranging specialist high-level access, which is planned with the client
- Joints whose design needs changing by the specifier
If you are not sure, just speak to us on 01277 525 020 or email us and we will give you a straight answer.
Joints and surfaces we work on
- Coping and flashing joints
- Cladding panel joints
- Window and door perimeters
- Stone and brick facade joints
- Shopfront frames
- Perimeter joints where frames meet the structure
Diagnose, treat, sign off
When we get to site, we report to your site contact and complete whatever induction the building runs. Everything around the joints gets protected before anything is cut or cleaned, with the work itself usually taking longer on a full elevation than on a handful of window perimeters, and it always depends on dry weather. Jobs in and around smaller places like Crockham Hill are typically planned as a single visit, so photographs and measurements up front really help. That way the right products come on the day.
- We plan access and the order of elevations with the client.
- Weather and temperature are checked against the product’s limits.
- Each joint is cut out and the edges inspected.
- Faces are cleaned, primed where needed and backed.
- Sealant is gunned in and tooled hard onto both faces.
- Once signed off, the work carries our 12-month guarantee.
Before we start on site
- Explain the parking and delivery arrangements
- Flag any permit to work we’ll need
- Have the specification and drawings to hand
