Blocks and managed buildings in Todd's Green
Rainfall across the South East, Todd's Green included, is lower than in many parts of the UK. Outside mastic still needs a dry joint and the right temperature, while the elevations that take the most sun tend to show hardened mastic first. At about 30 miles from central London, Todd's Green is within reach of the capital. Commuter-belt towns tend to have plenty of managed blocks near stations and town centres.
Older buildings near Todd's Green, from historic houses such as Knebworth House (to the south of Todd's Green) to more modest stock, need compatible products when frames are resealed. If your remit includes a building such as The John Henry Newman School, frame and door mastic can be programmed for the holidays. Older community buildings, Church of St Mary the Virgin among them, often have frames of mixed ages whose mastic varies.

Mastic sealing for commercial buildings in Todd's Green
Older blocks and commercial buildings can have mastic that contains asbestos. Before we disturb it, we ask to see the asbestos register or survey and if it’s suspected, work stops until it’s tested. Removing asbestos-containing material isn’t something we do. Most enquiries involve repeated reactive repairs to the same buildings and open joints in brickwork or panels, on shopfronts below residential blocks, external wall and movement joints and balcony and threshold joints. A specialist sealant contractor works differently from a general builder: on jobs in Todd's Green, preparation and product choice get the time they need.
Rural conversions near places like Todd's Green often set modern frames into older stone, flint or brick. Perimeter mastic there has to grip an uneven face and suit the building’s character.
Guaranteed is the last step of every job. Our workmanship is backed for 12 months, and we explain exactly what that covers when we quote.

Cost factors for mastic joints
Quotes vary with the job. It mainly depends on:
- The product specified
- How accessible the joints are
- Whether the work must be split into stages
- Location, for remote and island sites
Cost follows what’s involved: stripping out, preparation, sealing, access and phasing. Call for a quote and we’ll explain how it’s made up.

A few photos plus some basic facts will normally do. It helps to include:
- Rough lengths or quantities, or drawings if you have them
- A wide shot and a close-up of the area

FAQs: Todd's Green
Does your area include sites such as Horizon Technology Park, near Todd's Green?
Yes, sites like Horizon Technology Park are within our area, along with the rest of Todd's Green. Send details of the unit and the work through our quote form for a quick quote.
Can you quote for a block close to Stevenage 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.
How long will the new sealant last?
It depends on movement, UV and weather, cleaning, traffic and the product. Sealant joints are maintenance items, so inspect them regularly.
How long does a job like this take?
That varies with the scale of the job, though a typical visit usually takes a day or two for a single block, longer for an estate programme. For bigger or phased jobs, we’ll set out a timescale with the quote.
Do you cover Todd's Green?
Yes. Todd's Green falls within our area, and you can phone 01277 525 020 or send photos by email to get started.
Can you work to our specification?
Yes. The specification and the manufacturer’s installation guidance are what we work to.
Is asbestos a concern with old mastic?
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.
Work for main contractors and building owners
If you look after buildings for someone else, 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.
Building owners and managing agents use us on sealant work across single buildings or whole portfolios around Todd's Green. Several sites can go on one quote, so there’s one set of paperwork to deal with.
Aftercare for building managers
After handover, a little attention goes a long way:
- Prioritise elevations facing the weather
- Mention RAMS, insurance or CSCS requirements up front
- Plan resealing building by building rather than complaint by complaint
- Log resealing dates block by block
Our workmanship is covered for 12 months, so report any failure in that time. After that, regular inspection keeps the programme on track.
Budgets are easier to plan when sealant is part of planned maintenance. A programme can start with the worst buildings and work down the list.
What happens if it’s left?
Reacting to every complaint means sending someone out block by block. Planned resealing covers a whole building or estate in one go, under a single quote and a single programme. One visit to deal with every failing joint makes more sense than several trips to a place like Todd's Green, rather than one at a time. Send photographs of each area and we’ll quote for the lot.
We don’t publish prices, because the scope varies so much from one building to the next. Call for a quote and we’ll price your job on its own details.
Why us?
- CHAS accredited contractor
- Colours confirmed for the specified product
- Joints cleaned back to sound surfaces
- Matching to RAL references, product permitting

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, which is what makes a joint last.
Paperwork matters too. Many sites expect CSCS cards, RAMS and proof of insurance, and our CSCS-carded applicators are used to working under those rules.
