Sites and facades in and around Tower Hill
The South East is one of the drier parts of the UK. Even so, frost and condensation on steel and glass are common on winter mornings, which is why external dates are agreed with the site manager. A number of hotels sit less than 2 miles from Tower Hill. Hotel refurbishments often run to tight programmes between busy periods, and perimeter and sanitary sealant has to keep up.
When a school such as St John's Catholic Primary School is extended or refurbished, the mastic package is often squeezed into the holidays. Further education sites such as The College of Richard Collyer, 1.5 miles to the north-east of Tower Hill, are extended and refurbished from time to time, with mastic often programmed into the summer break.
Tower Hill is about 1 mile south-west of Horsham, in West Sussex. Anywhere in RH13, the process is the same: details in, fixed quote out, then sealing and a 12-month guarantee. We work across 373 places in West Sussex. There’s a separate page for Brighton, about 18 miles away.

Facade sealing in Tower Hill, done properly
Facade sealants sit in the sun, rain and frost every day, so they don’t last indefinitely. Life depends on movement, weathering, product choice and the quality of the original work. When the time comes, we cut the old sealant out completely and start again. If you have hard, chalky sealant that no longer flexes and leaks at window and door perimeters, we can put it right, whatever the surface. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, in Tower Hill it comes down to the same thing: failed joints cut out, faces prepared and the right sealant laid to the right depth.
Conversions of older rural buildings near smaller places such as Tower Hill bring stone, flint, brick and timber up against new glazing. A product that grips an irregular face, with a colour that suits the building’s character, is usually what’s needed.
What our 12-month guarantee covers is the way we did the job: preparation, application and finish. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

Diagnose, treat, sign off
Before any cutting starts, the area is protected: tape along each joint edge and covers over finishes, stock and equipment close by. On site, the work typically takes anything from a single day to several weeks, depending on joint lengths, access and the weather, and our waste is bagged and taken away as we go. Rural sites near Tower Hill may need directions, gate codes or a contact on site. Add it to your enquiry and we will build it into the plan.
- Access, site rules and timing are settled with the client up front.
- We only seal when joints are dry and within the product’s temperature range.
- We remove the old bead and check the edges are sound.
- Joints are cleaned, primed if required and fitted with backing rod.
- Sealant is gunned in and tooled hard onto both faces.
- We hand over with our 12-month workmanship guarantee.

Advice
Common questions from Tower Hill clients
Is hospital work, at somewhere like Horsham Hospital, something you do?
Yes, healthcare and care buildings are part of our work. Work is phased so departments keep running, under the site’s own rules.
Is Tanbridge Retail Park, near Tower Hill, within your area?
Yes, sites like Tanbridge Retail Park are within our area, along with the rest of Tower Hill. Send details of the unit and the work through our quote form for a quick quote.
Can you handle several sites?
Yes. A group of buildings can go on one quote, with one point of contact.
Which sealant do you use on facades?
Low-modulus, neutral-cure silicone suits many facade and perimeter joints. Some joints call for hybrid, PU or polysulphide instead, as the specification or substrate requires.
How do I request a quote?
You can use the quote form on this site; alternatively, give us a call on 01277 525 020 or send details through our quote form. Photos, drawings or a joint schedule help us quote quickly.
Is it fine to apply new sealant on top of old?
No. Failed sealant is removed and the faces cleaned back to sound, dry material first, because fresh silicone will not bond with aged silicone.
Do you hold CHAS accreditation?
Yes. Mastic Doctor is CHAS accredited and a Constructionline member, which helps with supplier vetting.
Cost factors for facade joints
These are the things that shape the price:
- The size and state of each joint
- Which sealant the job calls for
- Whether old sealant has to be cut out first
- Distance, for remote addresses
Pricing facade joints depends on how many there are, their condition and the access, plus any specification you’re working to. Call for a quote.
What we need to price the job
To price the job accurately, we need to understand the site. Send us:
- Where the site is, with the postcode
- Any specification or named product
- Asbestos survey details if the building is older
- Rough lengths or quantities, or drawings if you have them
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 send photos by email to discuss it first.
How the job changes by surface
Brick and stone facades
Brick and stone facades have perimeter and movement joints that need a compatible sealant. We avoid acetoxy silicone, which can stain some natural stone.
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 with a product suited to glazing perimeters.
Leave it or put it right?
Leaving failed perimeter sealant also makes the eventual job bigger: edges get wet, render and timber deteriorate and frames can move. Acting at the first sign of splitting keeps the fix simple. Halls, stores and units around places like Tower Hill may not be checked every day, so a failed joint can leak for a while before anyone sees it. Renewing joints in good time avoids the problem.
The work involved drives the cost: stripping out, preparation, sealing, access and phasing. Call for a quote.

Other services in Tower Hill
Commercial clients in Tower Hill
For main contractors, we work as the sealant subcontractor on new-build and refurbishment projects. Programme, specification and site rules come first, with CSCS-carded applicators on site.
Blocks and communal areas make up much of the work for housing associations and agents. Work can be phased so residents and staff keep access throughout, and each stage is agreed with your contact.
When to call us in Tower Hill
Sometimes the substrate is the problem: crumbling render, spalling concrete or flaking paint take the sealant with them. When the joint edges need repair first, we say so.
Typical triggers for a call:
- Leaks at window and door perimeters
- Sealant pulling away from frames or panels
- Failed seals around shopfront and entrance frames
- Old perimeter mastic that has dried out
Hotel extensions and refits, at places such as The King's Head Hotel (0.8 miles north-east of Tower Hill), normally run between busy periods, so the sealing is squeezed into short windows.
