Plumber Services for All Your Home Needs
Water problems never arrive at convenient times, which is why our plumber team responds quickly to everything from small drips to major pipe bursts. We arrive ready to fix most issues on the first visit with our well-equipped service vehicles. From toilet backups to hot water heater failures, our experienced technicians handle each job with care that prevents future complications.
Many Denver homes have unique plumbing configurations due to their age - challenges our team addresses with effective, long-lasting solutions. We respect your property throughout our work, using protective coverings to keep your home clean while resolving your water issues.
Drainage Service to Protect Your Property
Blocked drains and sewer line issues can quickly cause expensive damage if not properly addressed. Our drainage service team uses video inspection equipment to pinpoint blockage locations without guesswork. We clear stubborn clogs using professional tools that solve problems without harming your pipes. For homes with ongoing drainage problems, we identify and fix the underlying causes rather than offering temporary solutions. We provide maintenance programs designed to keep your drains and sewer lines flowing freely throughout the year, preventing costly emergencies.
-
A plumbing emergency typically involves situations that threaten your property with water damage or create health hazards. These include burst pipes, major leaks that can't be stopped by shutting off a local valve, sewage backups, complete drain blockages causing overflow, and no water throughout your entire house. If you're unsure, call us—we can help determine if you need immediate service.
-
Due to the after-hours nature of the work, emergency plumbing service in Denver typically costs more than regular business-hour appointments. Exact pricing depends on the specific problem, necessary repairs, and the time required to fix it. Allen Service always provides upfront pricing before beginning work, so you'll know exactly what to expect. We never surprise customers with hidden fees or charges.
-
No, you should not call 911 for plumbing emergencies. Emergency services should only be contacted if there's an immediate threat to life or safety. For plumbing emergencies, call a professional emergency plumber like Allen Service directly. However, if your plumbing issue has caused a dangerous electrical situation or if gas leaks are involved, evacuate the home and call 911 first, then contact us.
-
Act quickly to minimize damage when facing a water emergency in your Denver home. First, locate and turn off your main water valve (usually near your water meter or where the water line enters your home). Move valuable items away from water if it is safe to do so. For localized issues like an overflowing toilet, close the fixture's shutoff valve instead. Soak up standing water with towels or mops to prevent further damage. Take photos for insurance purposes if needed.
-
Denver's climate creates unique plumbing emergencies. Winter brings frozen and burst pipes during cold snaps. Spring snowmelt often causes sewer backups as the ground becomes saturated. Water heater failures spike in winter when units work harder. Other common emergencies include water line breaks, major toilet clogs causing floods, and sump pump failures during summer storms. All require immediate attention to prevent costly water damage.
Any Budget Affordable Payments. Exceptional Service.
