Service entrance mast. Replaced and re-tied.
The riser pipe and weatherhead at the top of your service entrance. Weather, age, fallen branches, and roof work all damage them. Replacement coordinates with the utility, the inspector, and almost always involves a brief planned outage.
The mast is the most weather-exposed part of your service.
The riser pipe (mast) running from your meter up through the roof to the utility tie-in takes the full weight of the service-drop conductors, the wind load on those conductors, and the seasonal extremes of East Tennessee weather. After 20-30 years, most masts in our service area need replacement — rust, weatherhead failure, sealing rot at the roof flashing, or physical damage from fallen branches.
A mast replacement coordinates three parties: us (the electrician), the utility (TVA-LPC distributor — KUB, Sevier County Electric, Loudon Utilities, etc.), and your county inspector. The sequence: we pre-fabricate the new mast, the utility schedules a brief disconnect of your service drop, we replace the mast and riser (typically 4-6 hours from drop to re-energize), the inspector visits to sign off, and the utility re-energizes.
Most mast replacements are a same-day job once scheduled. The pre-coordination with the utility takes 1-2 weeks — they schedule disconnects in advance and have specific weather windows. We file the disconnect request, you pick a window that works, the utility crew arrives at the appointed time and pulls the drop. Then we work fast.
For storm-damaged masts (visible bend, leaning, broken weatherhead, fallen tree on the line), we treat as emergency — same-day if the utility can clear a crew, otherwise next-business-day. We coordinate the inspection retroactively.

Mast replacement scope.
Pre-fab + utility scheduling
We pre-fabricate the new mast assembly, file the disconnect request with your utility (KUB, Sevier Co-op, Loudon Utilities, etc.), and schedule the brief outage in advance. You pick the disconnect window.
2″ galvanized rigid pipe
NEC-spec 2-inch rigid metal conduit (RMC) or larger if your service is over 200A. Galvanized for corrosion resistance, sized for the service amperage, height calculated for proper drip-loop on the service drop.
Weatherhead + drip loop
New weatherhead at the top, proper drip loop on the service-drop conductors, sealed entry into the riser pipe. The weatherhead is the most failed component in old masts — we replace it every time.
Roof flashing + sealing
New roof flashing around the mast penetration, butyl-tape sealing under the flashing, sealed at the riser pipe. Stops the leak that comes with replacing an older mast where the old flashing is rotting.
Meter base replacement (when needed)
If the meter base is the same age as the mast and shows weather damage, corrosion, or worn meter sockets, we replace it as part of the same outage window. Adds 1-2 hours to the job.
Inspection walkthrough
County electrical inspector visits to sign off on the new service entrance — mast height, weatherhead, ground attachment, meter base, and bonding. Usually next-business-day after the mast install.

A tree took out our mast in an ice storm. KUB cleared a crew on a Wednesday, Volt Pro had the new mast prefabbed and ready, replaced it in four hours, inspector signed off Thursday. We were back on power before the next freeze hit.
Five things we get asked every week.
My service mast is leaning — is that an emergency?
How long does mast replacement take?
How much does a mast replacement cost?
Will my power be off during the replacement?
Do you handle the utility coordination?
Storm-damaged or aged-out mast?
