What happens if it’s left?
Piecemeal repairs over the years often leave mismatched sealant. Resealing a whole building gives a consistent finish. Converted and older buildings near places like Monkswood tend to move, and aged sealant cracks. A sealant with the right movement capability, correctly sized, lasts far better.
Whether it’s a single area or a whole estate, the same things set the price: scope, access, product and programme. Call for a quote, and you’ll have a fixed figure to work with.
Why us?
- One number for every site we cover
- Clear, fixed quotes

Mastic sealing in Monkswood, done properly
Across Monkswood and the rest of Hertfordshire, we work the same way: send details, get a fixed quote, we seal, and the work is guaranteed. Addresses, photos of typical joints and a rough idea of quantities let us give a quick quote or we can visit. The enquiries we see most involve damp patches beside frames and communal area joints that look neglected, across balcony and threshold joints, external wall and movement joints and shopfronts below residential blocks. 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.
Around smaller places like Monkswood, older walls fitted with newer windows are a familiar sight. Perimeter mastic there has to grip an uneven face and suit the building’s character.
A 12-month guarantee applies to all our work in Hertfordshire. If an installation problem shows up, speak to us on 01277 525 020 or email us and we will arrange a return visit.

Frames, entrances and external joints in Monkswood
Rainfall across the South East, Monkswood included, is lower than in many parts of the UK. Outside work still depends on dry joints, while the elevations that take the most sun tend to show hardened mastic first. There are two care or nursing homes within about 2 miles of Monkswood. Owners of care premises can bring window and door mastic into a phased programme planned around the home.
Student accommodation around universities such as University of Hertfordshire, 4.2 miles south of Monkswood, is normally managed block by block, which suits a planned mastic programme.

Do you need mastic sealing in Monkswood?
Communal entrances and corridors see a lot of wear, and low-level joints get damaged. Cleaning products add to the wear.
Typical triggers for a call:
- Failed external movement joints
- A mix of products and colours from past repairs
- Draughts at frames across a block
- Complaints coming in block by block
For agents with blocks near Welwyn North station (0.6 miles north-east of Monkswood), a block-wide mastic programme deals with frames, balconies and entrances in one go.
Before you book anyone
- How long is the guarantee, and what does it include?
- Whether old or failed sealant will be cut out, not overlaid
- Will RAMS and insurance details be available?
- Is depth set with backing rod, or bond-breaker tape in shallow joints?
What sets the cost
Each job is priced on its own details. The main factors are:
- Location, for remote and island sites
- How much there is to seal
- The size and state of each joint
- The site’s rules and procedures
What a job costs comes down to how many linear metres there are, how much old material needs removing and the access. Call for a quote once you have the details.
Before you send an enquiry
A good diagnosis starts with the right details. Let us know:
- Specification clauses that apply
- Whether an asbestos survey exists
- The type of building and who uses it
- Approximate linear metres or a joint schedule
If there’s a specification, drawings or a tender package, send it with your enquiry, and we will price against exactly what is specified. Smaller jobs need nothing more than photos and a few notes.
Common questions from Monkswood clients
Will you take on work at estates like Little Ridge Industrial Estate, close to Monkswood?
Yes. Estates, retail parks and business parks around Monkswood, Little Ridge Industrial Estate among them, are all within reach. Send details of the unit and the work through our quote form for a quick quote.
Can work in a care setting near Monkswood go ahead while residents are there?
Yes, with the manager deciding the order and timing of rooms. Any site rules, from signing in to infection control, are agreed before we start.
Is asbestos a concern with old mastic?
In older buildings, old mastic can contain asbestos. We ask for the asbestos register or survey before work starts and suspect material is tested first.
Can you quote from photos?
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.
Do you work in Monkswood?
Yes. We cover Monkswood, within our coverage of Greater London, South East England and Scotland. For a quote, call 01277 525 020 or email us.
How long before the joints can be used?
We’ll confirm how long the chosen product needs to cure, and flag anything to keep off until it has cured.
What do you charge?
We don’t publish prices, because every site is different. Send photographs or drawings and we will price it at a fixed figure.

General trades versus a specialist
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.
The visible bead is only part of the job. Correct depth, the right primer and a sealant matched to the movement are easy to get wrong without experience.
Looking after the joints
Regular inspection catches problems early. In particular:
- Track which buildings were done and when
- Keep bins and bikes away from communal door frames
- Share your contractor requirements early
- Include mastic in your cyclical inspections
Include sealant in planned building inspections. Check for splits, open joints, brittle mastic and lifting edges and record where they are.
Leaks at window perimeters spoil finishes and can affect frames. Early resealing is far simpler than repairs inside.
Diagnose, treat, sign off
The first thing on site is a walk round with your contact, to confirm the scope, the order of work and any areas we must keep clear. After that, any old or failed material is removed, each joint is prepared and the new sealant goes in. For work around Monkswood, we aim to finish in one visit, so we ask for photographs and rough sizes first. That way the right products come on the day.
- A building-by-building inspection lists the failed joints.
- You get a fixed quote, per block or for the whole programme.
- We agree the programme and dates with you.
- Old mastic is removed and the joint faces prepared.
- Joints are resealed and tooled.
- Each building is checked and signed off with the 12-month guarantee.
What we need from you
- Have the specification and drawings to hand
- Tell us what induction or permit system the site runs
- Point out any areas we must not close
