About our facade sealing in Monkswood
Facade joints are the line of defence between the weather and the building fabric. When a perimeter bead splits or peels, water finds its way behind frames and into the structure. We cut out failed facade joints and reseal them with a facade-grade sealant suited to the movement. We work on cladding panel joints, stone and brick facade joints and window and door perimeters, and the failures we are asked to look at most are perimeter sealant that has split or peeled away and perimeter joints where frames meet the structure. Facilities teams, main contractors and managing agents in Monkswood tend to want the same three things: a clear scope, tidy work and joints that don’t fail again.
For a site near Monkswood, the mastic visit is planned so the right sealants, primers and backing rod are on hand. Drawings, photographs and the programme let us give a fixed quote.
A 12-month guarantee applies to all our work in Hertfordshire. If an installation problem shows up, phone 01277 525 020 or send details through our quote form and we will arrange a return visit.

New build and refits around Monkswood
Monkswood has several hotels close by, all within 2 miles. When hotels extend or refit, the work is usually squeezed between peak periods, mastic included. The South East is one of the drier 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.
University estates such as University of Hertfordshire, 4.2 miles to the south of Monkswood, tend to have a rolling programme of new buildings and refurbishments, each with window perimeters and facade joints to seal. Hotel extensions and refits, at places such as The Wellington Inn Hotel, 0.9 miles north-west of Monkswood, typically run between busy periods, so the sealing is squeezed into short windows. Further education sites such as Oaklands College - Welwyn Garden City Campus (to the south of Monkswood) are extended and refurbished from time to time, with mastic often programmed into the summer break.
Monkswood is about 2 miles north of Welwyn Garden City, in Hertfordshire. Monkswood sits inside our coverage, and jobs here get the same fixed quote and 12-month guarantee as anywhere else. Our Hertfordshire coverage takes in 371 places. London is covered too, some 23 miles away.

How a job runs
When we get to site, we sign in, go through any site induction and check how permits are handled. Floors, finishes and fittings next to the joints are covered before anything is cut or cleaned, with the work itself typically taking a day or two for a few elevations, and longer where access has to be moved around the building. Jobs in and around smaller places like Monkswood are normally planned as a single visit, so photos and measurements up front really help. Then the right materials arrive with us.
- We start with photographs, drawings or a visit to see the joints and agree access.
- Product choice follows the joint’s movement and substrate.
- The existing bead comes out in full and both faces cleaned back.
- Primer is applied where the maker specifies it.
- Backing rod is fitted and the new sealant gunned in and tooled.
- We go over the completed work with you before leaving.
Getting the site ready
- Explain the parking and delivery arrangements
- Send any specification or drawings in advance
- Tell us your opening times and when work is allowed

What we can’t put right
We check first that sealant really is the fix. It isn’t the answer for:
- Movement beyond what any sealant can handle
- Damaged frames that need replacing
- Providing access systems for the work
If in doubt, call the office on 01277 525 020 or email us and we will say what we think.
Joints and surfaces we work on
- Stone and brick facade joints
- Perimeter joints where frames meet the structure
- Window and door perimeters
- Coping and flashing joints
- Cladding panel joints
- Shopfront frames
Why deal with it now?
Patch repairs over old sealant tend to come back. A full cut-out and reseal costs more on the day but lasts much longer, so you aren’t paying for the same joint twice. Around Monkswood, it’s better to renew all the failing joints at once. Photos of every joint help us quote for the whole job.
The product called for affects the cost, as does the preparation each joint needs, such as cutting out, priming or new backing rod. Access, phasing and site rules also count.
Why choose Mastic Doctor in Monkswood

Take a look at what affects the cost and our accreditations and insurance.
Surface by surface
Window and door perimeters
Window and door perimeters make up most facade sealing work. A low-modulus neutral-cure product, chosen for the frame and wall, goes in.
Cladding panel joints
On sealed panel systems, every joint keeps water out. Failed runs are cut out and rebuilt end to end with backing and a facade-grade sealant.
For managing agents and facilities managers
Main contractors use us as their sealant subcontractor. We work to your programme, your specification and your site rules, and our applicators hold CSCS cards.
As a CHAS accredited contractor and Constructionline member, we make supplier vetting simple. We’re fully insured, and our insurance certificate can go with the quote.
Your questions answered
Will you plan work around the academic year at somewhere like University of Hertfordshire?
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 Monkswood too small for you to travel to?
Not at all. Monkswood is within our area. Our area covers London and the South East counties. Where we can, we group nearby jobs to make the most of each trip.
Do you need to see the site first?
That depends on the size and complexity of the job. Straightforward work can often be priced from photos and measurements, while larger or less clear jobs get a site visit first.
How long before the joints can be used?
That comes down to the sealant and the temperature. Some products skin over quickly but need longer to cure fully, so we’ll confirm the curing time on the day.
Is it fine to apply new sealant on top of old?
No, never. Overlaying old sealant is a frequent cause of early failure, so everything comes out first.
Do you hold CHAS accreditation?
Yes. Mastic Doctor is CHAS accredited and a Constructionline member, which helps with supplier vetting.
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.
Doing it in-house
Redoing a failed joint typically costs more than getting it right at the outset, since all of it has to come out and the faces be cleaned back again. That’s why many clients bring in a specialist from the beginning.
For most general trades, sealant is a sideline. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint, which is what makes a joint last.
