Blocks and managed buildings in Cold Christmas
The South East is one of the drier parts of the UK. Outside mastic still needs a dry joint and the right temperature, and elevations facing the sun and the prevailing weather are usually where frame mastic ages first. At about 23 miles from central London, Cold Christmas is within reach of the capital. Around the capital’s commuter belt, managing agents look after many blocks close to stations and town centres.
If you look after a block within reach of Ware station (2.1 miles south-west of Cold Christmas), frame and balcony mastic can be renewed on one programme. Churches, halls and community buildings such as Parish Church of St Mary are looked after by trustees and committees like any other owner, and their frames, doors and external joints need mastic renewed in time. Older buildings near Cold Christmas, from historic houses such as Much Hadham Palace (to the north-east of Cold Christmas) to more modest stock, need compatible products when frames are resealed.

Mastic sealing in Cold Christmas
Our clients include managing agents, property factors in Scotland, housing associations and landlords with block or commercial portfolios. Many prefer a planned programme to one-off visits, with each block quoted and scheduled in turn. We work on balcony and threshold joints, communal entrances and stairwells and window and door perimeters on blocks, and the usual reasons a site gets in touch are complaints coming in block by block and window mastic that has split and shrunk. Looking for mastic applicators who cover Cold Christmas? We’ve been sealing commercial buildings since 2005, with CSCS-carded applicators.
Rural conversions near places like Cold Christmas often set modern frames into older stone, flint or brick. The mastic needs to suit an irregular masonry face and the look of the building.
Our workmanship is guaranteed for 12 months. If our installation lets you down in that time, we return and fix it.

What happens if it’s left?
Sealing over failed mastic looks tidy for a while. It doesn’t bond and usually fails within a short time. Cutting out and resealing properly does it once. One visit to deal with every failing joint makes more sense than several trips to a place like Cold Christmas, rather than one at a time. Send photos of each area and we’ll quote for the lot.
Every site prices differently: the joint sizes, the specified product, access and working hours each have a bearing. Send the details and a fixed figure follows.
What you get with us
- Clear, fixed quotes
- Fully insured, including public liability cover
- CSCS-carded applicators

Commercial clients in Cold Christmas
For main contractors, we work as the sealant subcontractor, on new build and refurbishment alike. Programme, specification and site rules come first, and our applicators hold CSCS cards.
Hospitality, education, healthcare, office and retail clients come to us directly as well. We plan around the way the building is used, so the building keeps working while we do.
Diagnose, treat, sign off
Diagnose, treat, sign off: that’s the shape of every visit. We inspect the joints and confirm what’s in scope, then the work is carried out to the specified product and detail, and the job ends with a walk round and sign-off. For work around Cold Christmas, we aim to finish in one visit, so we ask for photographs and rough sizes first. Then the right materials arrive with us.
- First we look at the mastic on each building and note what needs replacing.
- A fixed quote follows, split by block or building if that suits you.
- Dates, areas and access are agreed so residents or tenants can be told in advance.
- 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.
- Completed joints are inspected and carry a 12-month workmanship guarantee.
Getting the site ready
- Explain the parking and delivery arrangements
- Move anything stored against the joints
- Point out any areas we must not close

- Whether the work must be split into stages
- How accessible the joints are
There’s no price list, since every building and every scope is different. Call for a quote.
What we need to price the job
Good information means a firmer quote. Helpful details to send:
- Rough lengths or quantities, or drawings if you have them
- Any dates the work must fit around
- Whether an asbestos survey exists
- Where the site is, with the postcode
A good quote starts with a clear picture: the joints involved, quantities, access and the product called for. Send what you have, and we will arrange a site visit if anything is unclear.
Surface by surface
Window and door perimeters on blocks
Frames vary from uPVC to aluminium and timber, and the product is matched to the frame material and the masonry. Colours are confirmed for the product used.
External movement joints
Movement joints are cleaned out, backed with rod and resealed with a sealant of the right movement class.

Should maintenance staff do it?
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.
Using site staff can make sense for a small touch-up, but larger jobs are different: a specialist brings efficiency, a consistent finish and a 12-month guarantee.
Common questions from Cold Christmas clients
Will you take on work at estates like Thundridge Business Park, close to Cold Christmas?
Yes. Estates, retail parks and business parks around Cold Christmas, Thundridge Business Park among them, are all within reach. To start, just ring 01277 525 020 or email us with the unit, the joints involved and your access times.
Is Cold Christmas too small for you to travel to?
Not at all: smaller places are covered as well as towns. We work across Greater London and the South East. Where we can, we group nearby jobs to make the most of each trip.
Do you check for asbestos in old sealant?
We don’t remove asbestos-containing materials. If old sealant is suspected, work stops until it’s tested in line with the dutyholder’s asbestos management.
How do you reach windows on upper floors?
Access is discussed and agreed before the quote is fixed. Tell us the building height and any access already in place, and we’ll tell you how we’d approach it.
Can you send RAMS and CSCS details before starting?
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.
Who decides which product is used?
If the job is specified, we follow the specification. If not, we choose for the movement, the surfaces and the conditions, in line with the manufacturer’s guidance.
When can the area be used after sealing?
Curing time varies by product, and we confirm it on the day.
