How we handle mastic sealing in The Heath
For blocks and buildings in The Heath and across Hertfordshire, the process is the same: you send details, we return a fixed quote, the joints are resealed and the 12-month guarantee follows. A list of buildings, a few photos and approximate joint numbers are enough for a quick quote, and site visits can be arranged. If you’re dealing with no planned programme for sealant and occupiers reporting cold air round windows, we can put it right, whatever the surface. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, the work in The Heath is the same: the right product in a properly prepared joint.
In and around smaller places like The Heath, landlords and agents often look after small groups of housing association properties, converted farm buildings and community buildings. Mastic around frames and on external joints wears out in time, whatever the building.
Building owners and contractors get the same cover: twelve months on the work we carried out. Faults in the structure, damage and other trades’ work fall outside it, and we say so plainly.

What else we do in The Heath
Maintenance after handover
For the best life from the joints:
- Make mastic part of routine maintenance checks
- Group repairs into a planned programme
- Track which buildings were done and when
- Encourage occupiers to report problems at frames
Add mastic joints to your cyclical inspections. Watch for splits, open gaps, hard or chalky surfaces and mastic pulling away and record where they are.
Planned resealing is easier to budget than emergency repairs. A programme can start with the worst buildings so spending is spread.
What sets the cost
Your fixed quote is built from the real scope. It takes account of:
- Whether old sealant has to be cut out first
- The total length or number of joints
- The product specified
- The size and state of each joint
The specified product makes a difference, and so does the preparation, from cutting out to priming and backing rod. Access, phasing and site rules also count.
Before you send an enquiry
Whether it’s one area or a whole building, these details speed things up:
- Rough lengths or quantities, or drawings if you have them
- When you need the work done
- The site address and postcode
- Photos of the joints, close up and from further back
Pricing a project or setting a maintenance budget? Send the scope and any drawings, and we’ll return a fixed quote that you can work with. If you have questions first, ring 01277 525 020 or email us.

Advice
Your questions answered
We manage a building near Luton Airport Parkway 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.
Is The Heath off your patch?
No. Small places get the same service as large ones. We work across Greater London and the South East. Good photographs up front let us bring everything on the first visit.
Does weather matter for sealant work?
Outside, yes. Sealant needs a dry joint and a temperature within the product’s range, so frost, rain or cold mornings can delay outside work. Inside work is seldom held up.
How soon can the area be used again?
Curing time varies by product, and we confirm it on the day.
Do you supply RAMS and insurance details?
Let us know your requirements: tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we’ll confirm with the quote. We hold CHAS accreditation and Constructionline membership.
Is mastic sealing guaranteed?
Every building we reseal has a 12-month guarantee. It applies to our workmanship rather than damage or problems with the frames.
Will residents or tenants be disturbed?
Occupiers stay in the building throughout. If any flats or units need access, we will tell you in advance so it can be arranged.
When it isn’t the sealant
We seal joints; we don’t mend everything behind them. On its own, sealant can’t deal with:
- Cracked or crumbling render, brick or stone at the joint edges (we will tell you if so)
- Roof leaks, gutters or failed flashings that aren’t sealant joints
- Misted or failed double-glazed units
If you are not sure, just phone 01277 525 020 or email drawings and photos and we will give you a straight answer.
Where we work in The Heath

Frames, entrances and external joints in The Heath
The Heath sits in one of the drier corners of the country, the South East. Even so, frame mastic only goes on in dry, workable conditions, and south- and west-facing elevations, which take the most sun and rain, often age first. The Heath is about 29 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.
If you own or manage units on a site such as Barratt Industrial Park, 2.6 miles south-west of The Heath, failed mastic on frames, door surrounds and external joints can be dealt with unit by unit. For a school such as Breachwood Green Junior Mixed and Infant School, perimeter mastic on windows and doors is a holiday job.
The Heath is in Hertfordshire. Businesses, contractors and managing agents in The Heath use us for work on mastic joints. The Heath is one of 371 places in Hertfordshire on our list for mastic joints. Our London page has more on work in that area.

Local landmarks in The Heath
We work on buildings around Queen Elizabeth School and The Red Lion pub. The Heath’s nearest station is Luton Airport Parkway station, roughly 2.9 miles south-west. A little further out are The Mall Luton (3.6 miles west) and Keech Hospice Care (5.1 miles north-west). Open spaces near The Heath include Warden Hill and Pegsdon Hills.
Should maintenance staff do it?
Certain joints really need a specialist: 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.
Using site staff can make sense for a small touch-up, but anything bigger is another matter: a specialist brings efficiency, a consistent finish and a 12-month guarantee.
