Photos, a specification or a quick description of the joints is enough to start a fixed quote.
Aftercare for building managers
Every sealant joint needs some looking after, and their life depends on movement, exposure, cleaning and use. We suggest:
- Share access with other external trades
- Keep sills, gutters and drainage paths clear
- Investigate damp beside windows promptly
- Avoid patch repairs on failed facade joints
Hold back any cleaning crew until the joints have had their stated cure time. Keep high-pressure jets and strong chemicals away from new sealant, so brief your window cleaners.
Coordinate facade sealing with other external works. Sharing the access keeps the cost down.
Facade sealing in Baldock
Installing framed glazing systems isn’t part of our work. We handle the sealant joints that surround those elements: perimeter joints where frames meet the structure, panel joints and window perimeters. Most enquiries involve patch repairs that keep failing and hard, chalky sealant that no longer flexes, across stone and brick facade joints, coping and flashing joints and cladding panel joints. A single leaking joint is often how a building in Baldock first comes to us: we check the joints around it and give you an honest view of what needs doing now and what can wait.
Building work in places the size of Baldock is typically small-scale: a handful of new houses, barn conversions, a school or hall extension. Small schemes still need window perimeters, facade joints and internal sealant done to the specification.
What our 12-month guarantee covers is the way we did the job: preparation, application and finish. It doesn’t extend to damage, other trades’ later work or movement the joint was never designed to take.

Doing it in-house
General builders and handymen seal joints, but it isn’t their main trade. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint.
There’s also the paperwork. Many sites expect CSCS cards, RAMS and proof of insurance, and our CSCS-carded applicators are used to working under those rules.
What we are called out for in Baldock
New sealant run over old sealant rarely holds. Fresh silicone won’t stick to cured silicone, and the patch soon lifts.
If one of these sounds familiar, it’s time for a closer look:
- Hard, chalky sealant that no longer flexes
- Facade joints cracked through the middle
- Water coming in around window frames
- New sealant peeling off old mastic
For a contractor at a hotel such as The Old George And Dragon Hotel, which lies north-west of Baldock, the mastic often has to be finished before a reopening date.

What we can’t put right
Not every problem is a sealant problem, and we’d rather tell you before you spend money. These need a different solution:
- Specialist high-level access methods
- Replacing glass or failed glazing units
- Joints whose design needs changing by the specifier
Not sure which it is? You can call the office on 01277 525 020 or send photos by email and we’ll tell you honestly before you book.

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 a job in Baldock, the main thing is a clear picture of the work, so send photographs of each area. A fixed quote follows.
- We plan access and the order of elevations with the client.
- Weather and temperature are checked against the product’s limits.
- We remove the old bead and check the edges are sound.
- Joints are cleaned, primed if required and fitted with backing rod.
- Facade-grade sealant goes in and is tooled to a tidy concave profile.
- Once signed off, the work carries our 12-month guarantee.
What we need from you
- Confirm the product named in the specification
- Share the asbestos register for older buildings
- Let building users know which areas are affected

Facade sealing in Baldock: the local picture
Central London is about 34 miles from Baldock. Construction around the commuter belt mixes station-side flats with refurbished offices and units, and each scheme needs its mastic sealed to programme. Rainfall across the South East, Baldock included, is lower than in many parts of the UK. Still, external mastic needs dry faces within the maker’s temperature limits, which isn’t every day, so the external programme keeps a little slack.
For contractors at a school such as Hartsfield Junior Mixed and Infant School, sealing has to be finished before term starts. New units and refits on sites such as Letchworth Gateway Retail Park, 1.1 miles to the south-west of Baldock, need their panel and perimeter joints sealed to the specification.

Your questions answered
Can you work on a hospital site such as Fairfield Hospital?
Yes. Healthcare sites are among the places we work. We follow the site’s permits, sign-in and infection-control procedures in every area.
Does your area include sites such as Letchworth Gateway Retail Park, near Baldock?
Yes. Our area takes in Baldock and its surroundings, with estates and business parks such as Letchworth Gateway Retail Park included. Send details of the unit and the work through our quote form for a quick quote.
Does weather matter for sealant work?
It can, for external work. Wet joints and cold, damp or frosty conditions stop the sealant bonding properly, so we watch the forecast and rearrange outside work if we have to. Internal work is far less affected.
What’s the quickest route to a quote?
It works in four steps: send details, receive a fixed quote, we carry out the work, and it’s guaranteed. The first step only needs photos and a postcode.
Do you offer coloured sealant?
Often, yes. Sealants are made in a wide range of standard colours, and matching to RAL references or nearby finishes is commonly requested. We’ll confirm the colours available for the specified product.
Can you work in cold or wet weather?
Wet joints or temperatures outside the product’s range mean waiting. We plan for weather and keep you updated as the work goes on.
Which sealant do you use on facades?
Low-modulus, neutral-cure silicone suits many facade and perimeter joints. Hybrid or MS polymer, polyurethane and polysulphide sealants suit others, as the specification or substrate requires.
