How we handle construction mastic in Gundleton
Getting a subcontractor through site induction should be simple. We are a Constructionline member and CHAS accredited, and every applicator holds a CSCS card, and we’re fully insured. Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we will confirm with the quote. If you have bath and shower joints scraped during the final clean and window and door perimeters that won’t pass inspection, we can help, whatever the surface. Whoever orders the work in Gundleton, the brief is normally the same: a clear scope, tidy work and joints that don’t fail again.
Conversions of older rural buildings near smaller places such as Gundleton bring stone, flint, brick and timber up against new glazing. A product that grips an irregular face, with a colour that suits the building’s character, is typically what’s needed.
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.

Gundleton: questions and answers
Will you take on work at estates like Lower Soldridge Business Park, close to Gundleton?
Yes. Our area takes in Gundleton and its surroundings, with estates and business parks such as Lower Soldridge Business Park included. Send details of the unit and the work through our quote form for a quick quote.
Is a smaller place like Gundleton outside your area?
No. Small places get the same service as large ones. We work across Greater London and the South East. We plan jobs in smaller places so return trips are kept to a minimum.
When can the area be used after sealing?
The product and site conditions decide that. Some take light use quickly, others need longer to cure, so we’ll confirm the curing time on the day.
Can the sealant be colour-matched?
In many cases, yes. Many products come in a range of standard colours, and matching to RAL references or surrounding finishes is often possible. We will confirm the colours available for the specified product.
Can fire-rated sealing at service penetrations be included?
It can be part of the package where specified. Tell us what records you need and we’ll confirm with the quote.
Do you take on multi-site work?
Yes. We take on portfolio and planned maintenance work, planned site by site to suit how each building is used.
Can you follow the specification on our project?
Yes. Include it with the drawings when you ask for a quote, and the quote will be based on it.
Aftercare for building managers
Cleaning and maintenance staff play a part too. Share these points with them:
- Brief the final clean team to avoid blades near sealant
- Plan external elevations with the weather in mind
- Protect sealed areas from following trades
- Record the products used in the O&M file
At handover, keep the product details with the O&M information. Future maintenance is easier when the products are known. Tell us what records you need and we’ll confirm with the quote.
Leaving the mastic snag list to the end squeezes everyone. A planned close-out through each area as it completes keeps the list short and keeps handover on track.
What we can’t put right
Part of a good diagnosis is knowing where sealant stops. You will hear from us if the cause turns out to be any of the following:
- Joints damaged after sign-off by following trades
- Approving fire stopping as compliant
- Faulty frames rather than failed sealant
Not sure which it is? You can call the office on 01277 525 020 or email a schedule or drawings and we’ll tell you honestly.
Joints and surfaces we work on
- Cladding and panel joints
- Internal decorators’ caulk
- Window and door perimeters

- Floor and skirting junctions

Mastic packages on Gundleton sites
Gundleton is in the South East, one of the UK’s drier regions. Winter mornings still bring frost and condensation on frames and panels, so external mastic is timed for workable conditions and agreed with the site manager. Gundleton lies roughly 52 miles out from central London. Building activity in the commuter belt runs from new flats near stations to business park refurbishments, which keeps mastic packages in demand.
Units on estates such as Lower Soldridge Business Park, 2.3 miles north-east of Gundleton, tend to be reclad and refitted as tenants change, and each job leaves cladding and perimeter joints to seal. With historic properties like Hinton Ampner House, 4 miles to the south of Gundleton, in the area, refurbishment work often meets old masonry that needs compatible sealants.
Gundleton is about 7 miles south-west of Alton, in Hampshire. We send applicators to Gundleton for mastic packages. Across Hampshire, 723 places are covered, including Gundleton. For work in that direction, see our Southampton page, about 17 miles away.
Anyone looking for construction mastic in SO24 gets the same process as the rest of our area: details, then a fixed price, then sealing and a 12-month guarantee. Among the streets we cover are Goscombs Lane and Bighton Lane. If your building is just outside Gundleton, we cover Bishop's Sutton (1 mile south-west), New Alresford (2 miles west), Bramdean (3 miles south), Hinton Ampner (4 miles south) and Cheriton (4 miles south-west). A short drive away, we cover Basingstoke (12 miles north), Winchester (9 miles west), Eastleigh (13 miles south-west), Horndean (14 miles south), Chandler's Ford (14 miles south-west) and Alton (7 miles north-east).
Around Gundleton
We work on buildings around Three Horseshoes Public House and the streets around them. Other landmarks nearby include Barton Castle (2.9 miles north). Green spaces nearby include Shutts Copse and Red Hill.
Common problems we fix in Gundleton
Most mastic snags on new buildings come from sequencing rather than product. Sealing before decorators, flooring or other trades have finished leaves joints exposed to damage, and the joint has to be redone.
Common reasons buildings call us in:
- Window and door perimeters that won’t pass inspection
- A long mastic snag list close to completion
- Failed sealant in an existing building being refurbished
- Different trades sealing to different standards
For contractors at a school such as Perins School, sealing has to be finished before term starts.
What your quote should include
- Will CSCS-carded applicators be on site?
- How long is the guarantee, and what does it include?
- What site paperwork they can supply
- Their approach to joint depth and backing
General trades versus a specialist
For a quick touch-up, site staff may be fine, but anything bigger is another matter: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.
A short, simple internal joint is often within reach of a maintenance team. The usual problems come from preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.

What the job involves on each surface
Snagging before handover
Snagging is often the final mastic stage. We can work through the snag list area by area and damaged joints are redone rather than patched.
Bathrooms, en suites and washrooms
Across a block of flats or a hotel, sanitary sealing is repeated in every room. A single team keeps the standard consistent.
Diagnose, treat, sign off
Before we leave any area, the masking comes off, the area is cleaned and every joint is checked. If an area should be left alone while the sealant cures, we say how long and put signs out. Jobs in and around smaller places like Gundleton are typically planned as a single visit, so photos and measurements up front really help. Then the right materials arrive with us.
- We price from the drawings, specification and programme you send.
- A fixed quote sets out the scope, the products and the sequence.
- You tell us what site paperwork you need, such as RAMS, an insurance certificate or CSCS details, and we confirm it with the quote.
- Work follows the programme, area by area, as rooms and elevations become ready.
- Joints are cleaned, primed where the maker requires it, backed and sealed to the specification.
- We close out snagging and hand over with a 12-month guarantee.
Getting the site ready
