About our mastic sealing in Ridge
Treatment starts with a proper look: what has failed, what caused it and whether new sealant will actually solve it. Failed mastic is stripped, the faces taken back to sound material, primed where the manufacturer specifies and resealed and backing rod used wherever a joint is deep. Site teams most often ask us about no planned programme for sealant and occupiers reporting cold air round windows, across window and door perimeters on blocks, communal entrances and stairwells and external wall and movement joints. Facilities teams, main contractors and managing agents in Ridge tend to want the same three things: a clear scope, tidy work and joints that don’t fail again.
Around smaller places like Ridge, 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.
Every job ends the same way: guaranteed. You get a 12-month guarantee on our workmanship, and we explain exactly what that covers when we quote.

Leave it or put it right?
Draughts round window perimeters cost occupiers comfort, and they often blame the windows. Resealing the perimeters is often the simpler fix where the frames themselves are sound. Converted and older buildings near places like Ridge tend to move, and aged sealant cracks. The right product, sized to the joint, copes much better.
What a job costs comes down to the quantity of joints, what has to come out first and the access. Call for a fixed quote when you are ready.

On site: what to expect
Our CSCS-carded applicators arrive with the sealants, primers and backing rod the job calls for. Joint faces are cleaned back to sound, dry surfaces, primer goes on where the manufacturer specifies it, and each bead is tooled to a neat concave finish. For work around Ridge, we aim to finish in one visit, so photos and measurements up front really help. That way the right products come on the day.
- First comes a look at the joints and, for older buildings, the asbestos records.
- The products and programme are set out in a fixed quote.
- We strip out the old sealant.
- The joints are prepared and resealed with the right product.
- We finish each building before moving to the next.
Preparing the site
- Confirm the product named in the specification
- Move anything stored against the joints
- Tell us your opening times and when work is allowed

Every quote starts with the facts: what’s there, how much of it, how we reach it and what’s specified. Send what you have, and we will arrange a site visit if anything is unclear.

What we can’t put right
Our job is the joint, not everything around it. On its own, sealant can’t deal with:
- Cracked or crumbling render, brick or stone at the joint edges (we’ll tell you if so)
- Water coming in from the roof or rainwater goods
- Materials that need asbestos testing before work
If you’re not sure, just speak to us on 01277 525 020 or email a schedule or drawings and we’ll give you a straight answer.
Joints and surfaces we work on
- Balcony and threshold joints
- Window and door perimeters on blocks

Your questions answered
Is Ridge too small for you to travel to?
No. Small places get the same service as large ones. We work across Greater London and the South East. Good photos up front let us bring everything on the first visit.
Can you work at a site such as Borehamwood Industrial Park, by Ridge?
Yes. Our area takes in Ridge and its surroundings, with estates and business parks such as Borehamwood Industrial Park included. A few photos and the unit address let us price the work.
How much does the work cost?
That depends on the job: quantities, access, the product and any phasing. Call for a quote and we will price it properly.
How long do sealant joints last?
There’s no fixed lifespan: movement, exposure, cleaning, traffic and the product all play a part. Sealant joints are maintenance items, so inspect them regularly.
How many days will you need on site?
That varies with the scale of the job, but the work normally takes one or more days per building, depending on the joint lengths and the access. Larger or phased jobs take longer, and we will give you a timescale with the quote.
Do you need to see the site first?
It depends on the job. Simple work can often be priced from photographs, while larger or less clear jobs get a site visit first.
Do you take on small jobs?
Single areas, one-off repairs and whole buildings are all quoted the same way: details, then a fixed price, then sealing, then a 12-month guarantee.
What affects the price in Ridge
Sealant work doesn’t have a standard rate, since sites vary so much. What we look at:
- Travel to remote or island sites
- How much there is to seal
- Removal of failed or old sealant
- Joint width, depth and condition
Pricing mastic joints depends on quantities, condition and access. Ask us for a fixed quote.
Before you send an enquiry
A few photos plus some basic facts will normally do. Please tell us:
- What the building is and how it’s used
- Anything awkward about access or site hours
- Approximate linear metres or a joint schedule
- Any dates the work must fit around
Send us photos, drawings or a joint schedule are often enough for a fixed quote. If the job needs a look first, we’ll arrange a site visit.
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. For that reason, many FMs and contractors use a sealant specialist from the outset.
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.
For owners and agents in Ridge
Ridge is about 15 miles from central London. Commuter-belt towns tend to have plenty of managed blocks near stations and town centres; their frame mastic often ages block-wide. Ridge is in the South East, one of the UK’s drier regions. Even so, frame mastic only goes on in dry, workable conditions, while the elevations that take the most sun tend to show hardened mastic first.
Landlords with units on estates such as Borehamwood Industrial Park, 1.9 miles south of Ridge, can bring frame, door and external mastic across several units into one programme. For a school such as St Giles' CofE Primary School, perimeter mastic on windows and doors is a holiday job. If you look after a block within reach of Potters Bar station, which lies east of Ridge, frame and balcony mastic can be renewed on one programme.
Ridge is about 2 miles north-east of Borehamwood, in Hertfordshire. Our applicators travel to Ridge for work on mastic joints. Ridge is one of 371 places we cover in Hertfordshire for mastic joints. For work in that direction, see our London page, about 15 miles away.

Green spaces nearby include Darland's Lake and Furzefield Wood and Lower Halfpenny.
Different surfaces, different methods
Tenement and older buildings
Older buildings, including Scotland’s sandstone tenements, have their own joint details. The material either side of the joint shapes the product choice.
Commercial and mixed-use buildings
Mixed-use buildings combine shops below with flats or offices above, so phasing has to suit both. Tell us your site hours and access windows and we will plan around them.
