Cottrell & Co., Inc. Plumbing, Heating and Air is a full service residential and commercial plumbing, heating and air company that has proudly served the Columbia and Lexington areas since 1995. We have enjoyed building a reputation of excellence through quality parts, expert employees and maintaining high standards of workmanship. We pride ourselves in communication with our customers by listening, offering multiple solutions and always giving the price upfront. We also offer 24-hour emergency services.

"Do not use this company for backflow tests! I called Cottrell for a simple backflow device test. I was charged $213 for a backflow test which was over twice the amount I was told to expect by friends and family who had the same test done by other plumbers (one even showed me his invoice for $35.00). It is an absurd price for a very simple test and far overpriced compared to other plumbers in the area."

"I’ve had nothing but problems with SafeStreets. The installation was a mess—took hours longer than promised, and the technician seemed clueless about the system. When I called customer service, they were rude and unhelpful. The security system itself is glitchy and keeps going offline. Definitely not worth the hassle."

Nest Installation questions, answered by experts

The average cost of childproofing services is $410. This cost can range from $190 to $630 or more, depending on the size of your home and what services you need. 

The location of the childproofing additions also plays a vital role in the overall cost. For example, a bathroom is relatively small and costs about $150 to fully childproof. However, if you have a swimming pool, you could spend as much as $1,500 to $10,000 to make it entirely safe for small children, including adding a pool fence.

The best time to hire a childproofing professional is at least three months before your due date. Although it might seem early, proper childproofing takes time, especially if you need extensive services like a pool fence. Getting your house ready now before your child is on the go only helps to protect them at all stages of life.

In many cases, you can DIY home childproofing with success. You can purchase childproofing tools like cabinet locks, outlet covers, and table-edge guards and install them easily. 

However, it's best to have a professional childproofing service work on larger projects like pool safety or furniture anchoring. These safety measures can take a lot of time and effort to DIY, plus, you want to ensure the tasks are done correctly to keep your child safe.

While tamper-resistant outlets are effective at protecting children from the dangerous electrical outlets, few things can be truly childproof. Children may still try to imitate their parents and adults by inserting a plug into the tamper-resistant outlet. Hiding outlets behind childproofing covers is not an effective solution to this, as those covers can be removed or even swallowed. Tamper-resistant outlets are the safest option to keep children safe in your home, but be sure to always keep a close eye on young children around any outlets or electrical devices.

A professional childproofer will first survey your home to identify potentially dangerous locations, including stairs, cabinets, and pools. Once approved, your professional will order and install the safety equipment for you. 

Some ways a childproofing professional will make your home safe include:

  • Anchoring large furniture 

  • Installing safety gates

  • Installing safety latches on cabinets and drawers 

  • Covering railings that could trap a child

  • Covering electrical outlets 

  • Installing a swimming pool fence

  • Removing or covering electrical cords where possible
