Specialist lead flashings, valleys and chimney work. All to Lead Sheet Association standards. Covering SO40.
Tell us the job in 30 seconds. No pushy sales, no call-out fee.
Totton's damp Test Valley location accelerates the deterioration of lead flashing pointing — the mortar that holds lead step flashings into the brick course softens faster in the persistent moisture here than in drier locations. When the pointing fails, the lead lifts away from the stack and water tracks directly into the roof space. We carry out lead flashing replacement and re-pointing across all Totton property types.

Request Free QuoteLead flashings in Totton fail through three primary mechanisms: thermal movement cracking where flashing is fixed too tightly without movement provision, failed mortar pointing that secures step flashings to the brick course, and in Test Valley river humidity — one of the dampest locations in Hampshire, accelerated oxidation of the lead surface. On waterfront and exposed properties, the higher salt concentration in Totton accelerates surface deterioration faster than inland equivalents. We identify the failure mode during inspection and address the cause rather than patching the symptom with mastic.
Lead code specification is critical to longevity. Code 4 for step flashings and soakers. Code 5 for back gutters, valleys and bay roofs. Code 6 and above for parapet gutters and flat roof sections. We specify the correct code for each application — using undersized lead on a Totton property exposed to Test Valley river humidity — one of the dampest locations in Hampshire leads to early failure and repeat calls. All leadwork is carried out to Lead Sheet Association standards.
Mastic sealant applied over failed lead flashings is a temporary patch that lasts 2 to 3 years before failing again. Correctly dressed and fixed lead lasts 50 to 80 years. On any Totton property we work on, mastic is not used as a substitute for correct lead work. Where we find previous mastic applications, we strip them out and execute the junction correctly in properly dressed lead.

When a roof in Totton leaks near a chimney or valley, the lead is usually the cause. Here is how to tell failed leadwork from a covering fault.
When it is not the answer: A sound lead flashing that has simply lifted can often be re-dressed rather than renewed — we will not replace lead that has life left in it Read the full guide.
A free inspection of the roof and the loft void pins down what has failed and why on your Totton roof, so the quote is based on the real problem.
A written, itemised quote follows, with any access or scaffolding shown separately and nothing hidden in a lump sum. No call-out fee.
We fix a convenient date, keeping same-day slots open for genuine emergencies anywhere in Totton.
We strip the failed lead and dress new code-appropriate lead in correct bay lengths, to Lead Sheet Association detail, so it lasts decades not years.
We clear the site completely, show you what has been done, and hand over your workmanship guarantee.
| Job | Typical duration |
|---|---|
| Re-dress lifted flashing | 2–4 hours |
| Chimney flashing renewal | Half to 1 day |
| Lead valley replacement | 1–2 days |
| Bay roof or abutment leadwork | 1–2 days |
Wet or high-wind days pause work at height safely — we build weather margin into every Totton booking.
Leadwork at valleys and chimneys usually needs scaffold for safe access, itemised in the quote. Scaffold is specified for: chimney, valley and abutment leadwork above single-storey - always itemised in your written quote, never a hidden extra, and we arrange it.
Totton and Calmore have large post-war estates where scaffold access is straightforward but permits run through New Forest District Council. Pavement scaffold and skip permits go through New Forest District Council; allow a few working days on streets like Commercial Road, Rumbridge Street, the older streets near the Test where space is tight.
| Job | Typical range | Notes |
|---|---|---|
| Re-dress lifted flashing | £150–£350 | Per detail |
| Chimney flashing renewal | £350–£750 | Per stack |
| Lead valley replacement | £600–£1,400 | Per valley |
| Bay / abutment leadwork | £500–£1,200 | Scope dependent |
| Code-8 lead per detail | Quoted | Sized to LSA detail |
Worked example: a new dressed-lead valley on a 1960s semi at a post-war semi in Calmore in Totton: around £850 including access.
No deposit on standard leadwork; payment on completion. Written itemised quote, VAT included where applicable.
Covering SO40 and surrounding postcodes.
Leadwork is guaranteed for 10 years; correctly sized and dressed lead to LSA detail lasts far longer.
The workmanship is guaranteed for 10 years in writing across Totton, with manufacturer material warranties on top of that.
“The Lead Sheet Association specifies maximum bay lengths for each lead code to prevent thermal-movement fatigue cracking — the single most common cause of failed leadwork on older Southampton roofs.”— Lead Sheet Association (LSA)
Localised, external work — minimal noise and little waste — with no need to be home. You do not need to stay home for external work - we just need power and access agreed in advance.
Leadwork runs year-round; the junction is made watertight before we leave each day. Totton sits on the Test estuary edge, so waterfront properties see damp, salt-laden air and quick moss regrowth.
Chimney step flashing in Totton: £250 to £600. Back gutter: £200 to £450. Lead valley per valley: £400 to £1,000. Free no-obligation quotes on all leadwork.
Mastic is a temporary sealant that fails within a few years. Correctly dressed lead lasts 50 to 80 years. We do not use mastic as a substitute for lead work.
Yes. Lead flashing failure causing active water ingress is treated as an emergency — same-day attendance across Totton and all SO40. No call-out fee.
Code 4 for step flashings and soakers. Code 5 for back gutters and valleys. Code 6 for parapet gutters and flat roof work. We specify correctly for each application.
