Got a tire losing air near Metrotown, Deer Lake, or Brentwood? A leaking valve stem can turn into a flat fast. M7 Mobile Tire Service™ comes to you in Burnaby BC with tools to test the stem, replace the valve core, and set the right PSI. Need more help today? Visit our mobile flat tire repair services for quick service at home, work, or roadside.











A valve stem leak often feels like a mystery slow leak. You may top up air, then see the tire light again the next morning. Our tech checks the stem, cap, and core, then fixes the leak on the spot. We also follow basic tire pressure steps so your tire is not over or under filled. If the leak is not the stem, we can move to slow leak repair next.
First, we listen to what you noticed: air loss, hissing, or a TPMS warning. Next, we do a quick soap test around the valve stem and bead. If the core is loose, we tighten it with the right tool. If the stem is cracked, we replace it and recheck for bubbles. If you also found a nail or screw, we can switch to tire puncture repair without wasting time.
Burnaby roads can be tough on stems. Curb taps near Highgate or a worn cap can bend the valve and start a leak. Cold nights can also make old rubber crack. We will tell you if a simple core swap is enough or if the whole stem should be replaced. If the air is leaking from the rim edge instead, we may recommend bead leak repair to stop the bubbles.
Mobile valve stem service saves you a tow and a long shop wait. We work in driveways, parkades, and work lots in Burnaby. After the repair, we set tire pressure, check the other stems, and make sure the cap is snug. If you are also comparing tire patch cost or wondering how much to patch a tire, our tire patch services can be done during the same visit.
We arrive with a gauge, valve core tools, new rubber and TPMS-safe parts, and a compact compressor. We keep the job clean, so you can get back on Kingsway or Highway 1 without stress. If the tire leak is from a small tread hole, we can also provide tire plug services and explain tire plug cost vs patch options in plain words.
From Burnaby Heights to Edmonds and SFU, we come to where your car is parked. Many callers look up mobile tire repair when the tire keeps dropping a few PSI each day. That is why we test the valve stem first, then confirm the full tire is safe. If you drive on special tires, ask about run-flat repair so you do not damage the sidewall.

Valve stem repair cost depends on what failed. A loose valve core is quick, while a cracked stem or TPMS-style stem takes more parts and care. We give clear pricing before we start, so there are no surprises. If you searched tire repair near me, flat tire repair cost, or slow leak tire repair cost, we will explain what you actually need and what can wait.
Most leaks are slow. Check your tire pressure, then spray soapy water on the valve stem and around the base where it meets the wheel. If you see steady bubbles, air is escaping. Also watch for a TPMS warning that keeps coming back after you add air. In Burnaby, M7 Mobile Tire Service™ can test it properly and fix it without guessing.
It depends on how fast the air drops. If the tire is low, driving can damage the sidewall and make the tire unsafe. For a very small leak, you may be able to add air and drive a short, slow distance to a safe place, but avoid highway speed. If you are unsure, call for emergency flat repair in Burnaby so you do not risk a blowout.
Sealant can be a short-term rescue, but it can also make a mess inside the tire and may cause problems for TPMS sensors. If the leak is from the valve stem, sealant often does not fix the real issue because the air is escaping at the stem or the core. A quick on-site stem repair is usually cleaner and safer than driving around on a temporary fix.
Cost depends on the part and the wheel. Replacing a valve core is usually the lowest-cost fix, while a full stem replacement costs more, especially with TPMS parts. Mobile service also includes travel and on-site setup. We will quote it up front based on your car and location in Burnaby. If the leak is not the stem, we may suggest tire patch services or another safe repair instead.
