Sumer Electrical, Muar: electrical wiring, core drilling, wall cutting and leak injection

Sumer Electrical is a shop at Taman Sri Temiang in Muar that also takes wiring, core-drilling and waterproofing jobs. Its signboard calls it an electrical goods shop (Kedai Barangan Elektrik). About once a week it posts the same ad to a Johor Bahru renovation group and the national Pendawai Elektrik group. The ad offers electrical wiring, plumbing, non-vibration core drilling, concrete wall cutting, wall demolition and waterproofing by PU injection. Its Facebook profile lists service areas from Johor Bahru to Kuala Lumpur.

This page is built from its own Facebook posts and profile from January to October 2026, its Google Maps listing and a contractor directory. It describes what the business advertises, not work we’ve checked.

What it advertises

Its first ad in our data, on 1 January 2026, lists:

• electrical work
• non-vibration core drilling (水钻孔)
• concrete wall cutting
• PU-injection leak sealing
• grouting hollow (delaminated) tiles or render (空鼓灌浆)
• roof waterproofing coating

From 10 February 2026 the ad names electrical wiring work (拉电工程) and adds plumbing and wall demolition. That version was still running in its latest ad in our data on 8 October 2026. Its signboard also lists construction equipment and electrical goods.

Photos it posted as its work

Wiring heads its regular service-list ad, but most photos on its posts show other work: holes cored through walls and slabs with a drilling rig (June 2026), openings cut in walls (March 2026) and PU foam injected along leaking concrete joints (March 2026). Few show electrical work. We haven’t seen any of these jobs. If you need house wiring, ask about recent wiring jobs.

Area and prices

Its group ads name no area. Its Facebook profile lists Muar, Johor Bahru, Melaka, Seremban, Port Klang, Kepong and Kuala Lumpur. The same ad also appears in an Ipoh renovation group.

It doesn’t advertise prices; its ads ask you to WhatsApp. Our guides have no benchmark for core drilling or leak injection. For wiring, see house wiring prices in Malaysia.

The shop

Its Google Maps listing, which matches its phone number, places it at 6, Jalan Sri Temiang, Taman Sri Temiang, 84000 Muar. The listing gives hours of Monday to Saturday 9am–6.30pm and Sunday 10.30am–3.30pm. Its own photos there show the signboard and an open shopfront with cable reels, pipes and a power-tool banner. They also show a core-drilling rig bolted to the outside wall of a house.

The signboard and its Facebook profile give the business registration number 201203124292 (JR0030234-V). MyDigital Contractor, a contractor-directory site, shows a CIDB contractor registration for Sumer Electrical in Johor. It gives grade G3, member since June 2016, valid to August 2027. We haven’t checked this on CIDB’s own site. CIDB registration covers construction contracting (the listing’s categories include mechanical and electrical); it isn’t a Suruhanjaya Tenaga electrical-contractor registration.

Register check

None of 019-776 4911, 013-779 4911, the name Sumer Electrical or its registration number appears in Suruhanjaya Tenaga’s public registers of electrical contractors and competent persons (snapshot of 6 October 2026). That doesn’t prove the person doing the work isn’t registered. Registered wiremen and contractors are listed under their own name, company and phone, which can differ from a shop’s. For wiring work, ask which registered wireman will test and sign off the job. Our JB electricians guide explains the check.
