About our mastic sealing in Broxbourne
There isn’t one mastic for every joint on a building. Window perimeters and external joints often take a low-modulus neutral-cure silicone, and MS polymer sealants stick well to many substrates and often take paint. We will confirm the colours available for the specified product. If you are dealing with worn sealant at communal door frames and patchy repairs in mismatched sealant, we can help, on balcony and threshold joints, shopfronts below residential blocks and window and door perimeters on blocks alike. Looking for mastic applicators who cover Broxbourne? Mastic Doctor has worked for contractors, FMs and building owners since 2005.
In a smaller place such as Broxbourne, landlords and agents tend to look after small blocks, flats over shops, sheltered housing and commercial units. Their window perimeters and external joints need renewing as the mastic ages.
Whoever the client is, the cover is the same: a 12-month guarantee on our workmanship. It doesn’t extend to damage, faults in the building or work by others, and we are upfront about that.

For managing agents and facilities managers
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.
Blocks and communal areas make up much of the work for housing associations and agents. Work can be phased so residents and staff keep access throughout, and each stage is agreed with your contact.
What happens if it’s left?
Mixed repairs by different contractors leave a patchwork of products and colours. A block-wide reseal gives one product, one colour and one guarantee. Sealant hardens, cracks and loses grip with age, UV and movement. Renewing it in good time keeps the building weathertight.
The work involved drives the cost: removing old material, preparing the joints, the product, the access and how the work is phased. Call for a quote.

Different surfaces, different methods
Window and door perimeters on blocks

Common questions from Broxbourne clients
We manage a building near Broxbourne station. Can you help?
Yes. Managing agents, landlords, property factors and housing associations are who this service is for. We work to your notice and access arrangements.
Do you cover business parks and estates near Broxbourne, such as Hilgrove Business Park?
Yes. Estates, retail parks and business parks around Broxbourne, Hilgrove Business Park among them, are all within reach. A few photos and the unit address let us price the work.
Can you follow the specification on our project?
Yes. Include it with the drawings when you ask for a quote, and the quote will be based on it.
Will you just go over the old sealant?
No. Sealing over old material is one of the classic causes of early joint failure, so it all comes out first.
How soon can the area be used again?
The product and site conditions decide that. Some take light use quickly, others need longer to cure, so we’ll confirm the curing time on the day.
Can you send RAMS and CSCS details before starting?
Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we’ll confirm with the quote. We are CHAS accredited and a Constructionline member.
When is resealing likely to be due?
There isn’t a single answer, since movement, weather, cleaning and use all affect it. Regular inspection is the best way to catch problems early.
General trades versus a specialist
There’s also the paperwork. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and we’ll confirm the paperwork you need with the quote.
Putting right a botched joint often costs more than sealing it well at the start, 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.
On site: what to expect
We follow your site rules from the start: sign-in, induction and whatever permit system the building uses. Once we are cleared to begin, we take the joints in the sequence agreed with you, and each area is checked before we leave it. For a job in Broxbourne, the main thing is a clear picture of the work, so send photos of each area. You’ll then get a fixed price for the work.

Looking after buildings in and around Broxbourne
Broxbourne is in the South East, one of the UK’s drier regions. Outside mastic still needs a dry joint and the right temperature, and south- and west-facing elevations, which take the most sun and rain, often age first. Central London is about 18 miles from Broxbourne. Commuter-belt towns tend to have plenty of managed blocks near stations and town centres; their frame mastic often ages block-wide.
If you own or manage units on a site such as Hilgrove Business Park, which lies south-east of Broxbourne, failed mastic on frames, door surrounds and external joints can be dealt with unit by unit. Trustees of buildings like Church of St Augustine can bring frame and external mastic into a planned maintenance list. If you look after a block within reach of Broxbourne station, 0.5 miles to the east of Broxbourne, frame and balcony mastic can be renewed on one programme.
