New build and refits around Henley-on-Thames
Henley-on-Thames 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. Plenty of hotels sit less than 2 miles from Henley-on-Thames. When hotels extend or refit, the work is usually squeezed between peak periods, mastic included.
Hotels like Imperial Hotel And Associated Buildings (to the north-east of Henley-on-Thames) rarely close for long, so refurbishment mastic is phased floor by floor. With historic properties like Greys Court, 2.3 miles to the west of Henley-on-Thames, in the area, refurbishment work often meets old masonry that needs compatible sealants. Extensions at sites like Townlands Memorial Hospital, 0.5 miles north of Henley-on-Thames, typically sit beside working departments, and the mastic follows strict access rules.

Surface by surface
Window and door perimeters
Frame materials vary, and so does the preparation. Primer goes on where the manufacturer specifies it for that substrate.
Precast concrete panels
Precast panel joints have to absorb thermal and structural movement. We use a sealant with the right movement capability, set over backing rod.
What we can’t put right
Honesty saves time and money. Fresh joints won’t solve:
- Replacing glass or failed glazing units
- Movement beyond what any sealant can handle
- Providing access systems for the work
If you are not sure, just speak to us on 01277 525 020 or send photos by email and we’ll give you a straight answer.
Joints and surfaces we work on
- Cladding panel joints
- Stone and brick facade joints
- Window and door perimeters
- Shopfront frames
- Coping and flashing joints
- Perimeter joints where frames meet the structure
Doing it in-house
There’s also the paperwork. Many sites expect CSCS cards, RAMS and proof of insurance, and our CSCS-carded applicators are used to working under those rules.
The visible bead is only part of the job. Backing rod, primer where specified and a joint designed to move with the building are easy to get wrong without experience.

FAQs: Henley-on-Thames
Can you take on a job at a hospital such as Townlands Memorial 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.
Can work at a site such as University of Reading fit around teaching?
Yes. Education sites normally want the work in vacations or in phases during term, and we plan to suit. Any paperwork you need, from RAMS to our insurance certificate and CSCS details, is confirmed with the quote.
Are you CHAS accredited and on Constructionline?
Yes. We are CHAS accredited and a Constructionline member.
Can you just add new sealant on top?
No. Fresh silicone won’t grip cured silicone, so the existing bead is removed entirely and the joint cleaned back to sound material. Nothing else gives a bond that lasts.
Are you fully insured?
Yes. Mastic Doctor is fully insured, public liability included.
Who decides which product is used?
Where there’s a specification, we use the product it names. Otherwise, we recommend a product to suit the joint’s movement, the substrate and the conditions, following the manufacturer’s guidance.
When can the area be used after sealing?
The product and site conditions decide that. Some take light use quickly, others need longer to cure, so we will confirm the curing time on the day.
Leave it or put it right?
Topping up a failed joint normally buys very little time. A full cut-out and fresh bead is the repair that holds. For buildings in places like Henley-on-Thames, one well-planned visit beats several small ones, so we’d suggest renewing all the joints that are going, not just the worst.
The specified product makes a difference, and so does the preparation. Access, phasing and site rules also count.
