Why deal with it now?
On a refurbishment, there’s a choice between resealing existing frames and replacing them. If the frame is in good order, cutting out and resealing the perimeter can be all it needs, which is a much smaller cost. If the frame is life-expired, we will tell you. In a London building, a failed joint rarely affects only one party. Dealing with it early is simpler for everyone.
Larger quantities, tricky access or phasing all shape the price. Site requirements like inductions and permits play a part as well, along with the time of year for external work.

How we handle construction mastic in Friday Hill
External mastic depends on the weather in a way most internal trades don’t. Cold or damp mornings, frost and condensation on frames can all hold external sealing up so it helps to sequence elevations with some flexibility. Internal sealing often fills those days. We work on internal decorators’ caulk, window and door perimeters and floor and skirting junctions, and the failures we are asked to look at most are frame perimeters left unsealed or poorly sealed and mastic snags holding up handover. Searching for sealant specialists in Friday Hill? Mastic Doctor has worked for contractors, FMs and building owners since 2005, CHAS accredited and a Constructionline member.
Building sites in London tend to be tight: small compounds, delivery slots and shared hoists and scaffold. We fit around the programme, sealing each elevation or floor as other trades hand over.
We sign every job off with a 12-month guarantee. The promise is simple: if our work fails within that year, we put it right.

Common questions from Friday Hill clients
Can you work at a site such as Cork Tree Retail Park, by Friday Hill?
Yes. Our area takes in Friday Hill and its surroundings, with estates and business parks such as Cork Tree Retail Park included. To start, just ring 01277 525 020 or send details through our quote form with the unit, the joints involved and your access times.
Will you plan work around the academic year at somewhere like University of Portsmouth Walthamstow Campus?
Yes, holiday working periods are the norm on campus jobs. Any paperwork you need, from RAMS to our insurance certificate and CSCS details, is confirmed with the quote.
Does the weather affect the work?
It can, when the joints are outside. Wet joints and cold, damp or frosty conditions stop the sealant bonding properly, so external work may be moved if conditions aren’t right. Internal work is far less affected.
What site paperwork can you supply?
Requirements differ from site to site, so tell us what you need and we will confirm it when we quote.
How long do sealant joints last?
There isn’t a single answer, because life depends on how much the joint moves, how exposed it is and how it’s cleaned and used. Regular checks let you plan resealing before leaks or damage.
Can one quote cover more than one building?
Yes. Multi-site work and planned programmes are a core part of the service, planned site by site to suit how each building is used.
What hours do you work?
The office is staffed Monday to Friday, from 8am until 5pm. Tell us your site hours and access windows and the work will be fitted around them.

Hospitality, education, healthcare, office and retail clients book us directly too. We plan around the way the building is used, so guests, pupils, patients or staff are disturbed as little as possible.
When you manage a building on behalf of an owner, you need clear quotes and clear reporting. We quote a fixed sum, confirm the scope and walk the finished work with you or your representative, plus a 12-month guarantee.
Contractors’ notes for Friday Hill
Every borough of Greater London is inside the ULEZ, and that applies to contractors’ vehicles on any job in Friday Hill. Delivery slots and scarce storage shape how and when the mastic goes in. A number of hotels sit less than 2 miles from Friday Hill. Hotel extensions and refits normally have to fit around bookings, so mastic dates are tight.
For a contractor at a hotel such as The Castle Hotel (1 mile south-east of Friday Hill), the mastic often has to be finished before a reopening date. New wings at hospitals like The Holly Private Hospital (to the east of Friday Hill) bring long runs of window and panel joints to seal. When a college such as Sir George Monoux College (to the south-west of Friday Hill) builds or refurbishes, the mastic package typically has to fit around students and staff.

Different surfaces, different methods
Snagging before handover
Snagging is often the final mastic stage. Snags are cleared room by room, cutting out damaged joints and resealing them properly.
Internal decorators’ caulk
Where the specification calls for it, acrylic decorators’ caulk goes on non-moving internal gaps before painting. It’s for gaps that stay still and get painted, and we use a flexible sealant where there’s movement.
What sets the cost
To price the job, we consider:
- Quantities, in metres or numbers
- How much existing material needs removing
- Phasing around occupants
- How accessible the joints are
There’s no price list, since every building and every scope is different. Call for a quote.
Before you send an enquiry
To price the job accurately, we need to understand the site. Send us:
- Any dates the work must fit around
- The product your specification calls for
- Clear photographs of the problem areas
- The site address and postcode
Send us photographs, drawings or a joint schedule are often enough for a fixed quote. If the job needs a look first, we will arrange a site visit.
Looking after the joints
Keep the joints in good shape with a few simple steps:
- Don’t schedule sealing before decorators and flooring are done
- Share drawings and the specification as soon as possible
- Use the product the specification names
- Protect sealed areas from following trades
Expect some settlement in the first months. Flexible sealants in the right joints handle normal movement while rigid fillers and caulk can crack where movement is larger. We can advise if a joint needs a different product.
External joints sealed in poor weather are a common cause of early failure. Holding off until conditions suit avoids callbacks.

- Drawings, specification and programme come to us.
- Quantities are measured and a fixed price returned.
- We agree with the site team which areas come first.
- Each area is sealed when it’s released.
- Every joint is cleaned, set to depth and sealed with the specified product.
- After snagging, the work is handed over under our 12-month guarantee.
Before we start on site
