Facade sealing for commercial buildings in Great Wymondley
We don’t install glazing systems or replace glass. We handle the sealant joints that surround those elements: perimeter joints where frames meet the structure, panel joints and window perimeters with products suited to facade or glazing perimeter joints. If you are dealing with perimeter joints where frames meet the structure and water coming in around window frames, we can help, whatever the surface. Most enquiries from Great Wymondley start with one failed joint and grow into a wider look at the building: we check the joints around it and give you an honest view of what needs doing now and what can wait.
Around smaller places like Great Wymondley, building work normally means conversions of farm buildings, a few new houses or an extension to a hall or school. Each still needs a proper mastic package: window perimeters, facade joints and internal sealant to the specification.
A 12-month guarantee applies to all our work. If an installation problem shows up, phone 01277 525 020 or email a schedule or drawings and we will arrange a return visit.

After the work
To get the most from the new sealant:
- Keep pressure washers away from fresh sealant
- Inspect facade joints on a regular cycle
- Report water ingress at frames as soon as it shows
- Record the product and colour used on each elevation
Keep gutters, sills and drainage paths clear. Good drainage keeps water moving off the facade instead of soaking the joints.
Use each reseal to correct the joint: correct depth, proper backing and a sealant that can take the movement. A well-designed joint lasts longer than a like-for-like copy of a failed one.
Site staff or a sealant specialist?
Paperwork matters too. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and we’ll confirm the paperwork you need with the quote.
What you see is the finished bead, but most of the work is hidden. Correct depth, the right primer and a sealant matched to the movement are easy to get wrong without experience.

Our process
We schedule the visit to fit the site hours and access windows you give us. While we are working, the area stays contained and tidy, and your contact hears from us before we move to the next area. For work around Great Wymondley, we aim to finish in one visit, so photographs and measurements up front really help. Then the right materials arrive with us.
- Photos, drawings or a visit tell us about the joints and the access.
- We confirm the joint type, movement and the specified product.
- Failed beads are removed in full.
- Primer is applied where the maker specifies it.
- Rod goes in to fix the depth, then the joint is sealed and tooled.
- The finished joints are checked with you.
What we need from you
- Make sure the joints can be reached
- Send your site hours and access windows
- Let us know about inductions and permits

When something else is needed
Our job is the joint, not everything around it. Sealant alone won’t deal with:
- Providing access systems for the work
- Movement beyond what any sealant can handle
- Render or concrete edges that have broken away
Not sure which it is? You can speak to us on 01277 525 020 or email drawings and photos and we’ll tell you honestly.
What we seal
- Window and door perimeters
- Cladding panel joints
- Coping and flashing joints
- Perimeter joints where frames meet the structure
- Shopfront frames
- Stone and brick facade joints
How the quote is worked out
Each job is priced on its own details. The things that drive the figure:
- How much there is to seal
- Induction, permit and paperwork requirements
- Location, for remote and island sites
- Whether the work must be split into stages
The product called for affects the cost, as does the preparation each joint needs, from cutting out to priming and backing rod. Access, phasing and site rules also count.
Before you send an enquiry
It doesn’t need to be a full survey. These details are enough to start:
- Anything awkward about access or site hours
- A wide shot and a close-up of the area
- Your programme or deadline
- Approximate linear metres or a joint schedule
If there’s a specification, drawings or a tender package, send it with your enquiry, and we’ll price the work to it. For smaller jobs, photos and a description will do.
Questions about Great Wymondley
Is Letchworth Gateway Retail Park, near Great Wymondley, within your area?
Yes, sites like Letchworth Gateway Retail Park are within our area, along with the rest of Great Wymondley. Photos and a short description are enough for a first look.
Is a hospital such as Pinehill Hospital somewhere you can work?
Yes, hospitals are one of the sectors we cover. Each area is agreed with the ward or department and the estates team in advance.
Is any job too small?
Small jobs are welcome alongside larger packages. Photos and a description are enough to start.
Should we check old sealant for asbestos?
In older non-domestic buildings, old sealant can contain asbestos. Check the asbestos register or survey before it is disturbed. Removal of asbestos isn’t something we do.
When can you be on site?
Mention the site’s hours and access windows in your enquiry, and we’ll schedule the work to suit. Our office runs Monday to Friday, 8am until 5pm.
Do you work to architects’ specifications?
Yes. We follow the specification, along with the manufacturer’s installation guidance, and we raise anything unclear before work begins.
Are your applicators CSCS-carded?
Yes. Our applicators hold CSCS cards, as many construction sites ask for.
Leave it or put it right?
Open facade joints also let air and dirt through: occupants notice draughts and cold spots around windows. A new seal closes the gap for both. One visit to deal with every failing joint makes more sense than several trips to a place like Great Wymondley. Photos of every joint help us quote for the whole job.
Pricing facade joints depends on how many there are, their condition and the access, and any specification that applies. Ask us for a fixed quote.

Mastic packages on Great Wymondley sites
Rainfall across the South East, Great Wymondley included, is lower than in many parts of the UK. That doesn’t stop wet spells, or frosty starts that leave panels too damp to seal, so external mastic is timed for workable conditions and agreed with the site manager. Central London is about 31 miles from Great Wymondley. Building activity in the commuter belt runs from new flats near stations to business park refurbishments, and main contractors there need mastic that keeps to the programme.
On a healthcare site such as Pinehill Hospital, 1.3 miles to the west of Great Wymondley, new blocks and refurbishments go on while the hospital keeps running, so mastic work is sequenced carefully. Projects at colleges like North Hertfordshire College, 1.2 miles south of Great Wymondley, tend to run to term dates, so the mastic is planned tightly. Hotels like Needham House Hotel (0.9 miles south-west of Great Wymondley) rarely close for long, so refurbishment mastic is phased floor by floor.
