Mastic sealing for commercial buildings in Bedmond
Blocks are lived in, so access and disruption have to be thought through. The sequence, the areas and the dates are settled with you so you can let residents know what is happening. Entrances and stairwells are kept in use throughout. If you have open joints in brickwork or panels and no planned programme for sealant, we can help. Looking for mastic applicators who cover Bedmond? Mastic Doctor has worked for contractors, FMs and building owners since 2005.
For owners with a single building near Bedmond, we plan to finish in one visit where possible. Send photos of the frames and joints and we’ll give a fixed quote.

Doing it in-house
Some joints are best left to specialists: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. Getting these wrong typically costs more in the end than doing them right.
The visible bead is only part of the job. Backing rod, primer where specified and a joint designed to move with the building are where general trades tend to cut corners.
Work for main contractors and building owners
CHAS accredited and a Constructionline member, we are straightforward to vet for your supplier list. Our insurance certificate can be sent along with the quote.
For main contractors, we work as the sealant subcontractor. We work to your programme, your specification and your site rules, and our applicators hold CSCS cards.
When to call us in Bedmond
We often find joints filled solid with no backing rod so the mastic is bonded on three sides. That three-sided adhesion stops it stretching and splits as the building moves.
These are often picked up first by site or facilities staff:
- Draught complaints from residents or tenants
- Old repairs sealed over failed mastic
- Open joints in brickwork or panels
- Window mastic that has split and shrunk
If you look after a block within reach of Kings Langley station, 1.6 miles to the south-west of Bedmond, frame and balcony mastic can be renewed on one programme.

What affects the price in Bedmond
Each job is priced on its own details. The things that drive the figure:
- Working within restricted access windows
- Travel to remote or island sites
- Whether old sealant has to be cut out first
- The product specified
Pricing mastic joints depends on quantities, condition and access, plus any specification you are working to. Ask us for a fixed quote.
What to include in your enquiry
A few photos plus some basic facts will normally do. It helps to include:
- The postcode of the building
- Access details, including height
- Any dates the work must fit around
- What the building is and how it’s used
We quote a fixed sum against the scope you give us, so the cost is agreed before work starts. To start the process, call 01277 525 020 or email a schedule or drawings.
Diagnose, treat, sign off
The first thing on site is a walk round with your contact, agreeing which joints are in scope, where to start and what must stay open. After that, any old or failed material is removed, each joint is prepared and the new sealant goes in. If others near Bedmond need work, visits can be combined. A fixed quote is given before anything starts.
- Each block or building is walked and the failed joints recorded with the likely cause.
- You get a fixed quote, priced per building where that helps your budgeting.
- The sequence and the dates are fixed with you, giving you what you need to notify occupiers.
- We remove the old mastic completely and clean the joint faces back.
- Backing rod and primer go in where the joint and the product need them, then new sealant is applied and tooled.
- Finished joints are looked over and the 12-month guarantee confirmed.
Getting the site ready
- Share your working hours and any access restrictions
- Explain the parking and delivery arrangements
- Clear stock, furniture or equipment away from the joints
Request a quote
If there’s a specification, drawings or a tender package, send it with your enquiry, and we’ll price the work to it. For smaller jobs, photos and a description will do.
Advice

Why deal with it now?
Failed perimeter mastic lets cold air in around frames and the windows usually get the blame. Resealing the perimeters is often the simpler fix when the frames themselves are sound. Around Bedmond, it’s better to renew all the failing joints at once, rather than one at a time. Send photographs of each area and we’ll quote for the lot.
The specified product makes a difference, as does the preparation each joint needs, such as cutting out, priming or new backing rod. Access, phasing and site requirements come into it too.
Why appoint us
- Fully insured, including public liability cover
- A fixed quote before work starts
- One number for every site we cover
- CHAS accredited

Looking after buildings in and around Bedmond
Bedmond is about 20 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. Bedmond is in the South East, one of the UK’s drier regions. Even so, frame mastic only goes on in dry, workable conditions, and elevations facing the sun and the prevailing weather are typically where frame mastic ages first.
Older community buildings, Church of the Ascension among them, often have frames of mixed ages whose mastic varies. Older buildings near Bedmond, from historic houses such as High Elms Manor (1.5 miles south-east of Bedmond) to more modest stock, need compatible products when frames are resealed.

Questions about Bedmond
Can you quote for a block close to Kings Langley station?
Yes. Blocks of any size are within what we do. Give us the building’s details and say how residents are notified, and we will quote and plan to suit.
Does your area include sites such as Kings Park Industrial Estate, near Bedmond?
Yes. Estates, retail parks and business parks around Bedmond, Kings Park Industrial Estate among them, are all within reach. A few photographs and the unit address let us price the work.
Can weather delay the job?
Outside, yes. The joint has to be dry and within the product’s temperature range, so damp, frosty or very cold days can stop external work. Internal work is rarely affected.
How long does a typical visit take?
The duration is planned around your programme and the access we are given. We will give you an estimate of time on site when we quote.
Do you work for managing agents and housing associations?
We do. Most of our mastic sealing is for agents, factors, housing associations and portfolio landlords and work can be quoted per building or as a whole.
Do you work to architects’ specifications?
Yes. Include it with the drawings when you ask for a quote, and we will price the work to it.
What about access for upper-floor joints?
We talk through access for each building when we quote. Tell us the building height and any access already in place, and we will tell you how we’d approach it.
