"ET construction worked on our cottage this summer. ET replaced our old ceilings with knotty pine panels and upgraded our lights to ceiling fans. Also added more outlets. Also replaced outside siding. They were great to work with and efficient. I would recommend them. It’s hard to find someone that you can trust."

"We shopped and spoke with many "facade restoration experts" before choosing to work with High Tech and we are so glad we did our research. Shaiful was by far the most knowledgeable contractor we spoke with and made us feel confident that he was capable of solving our issues.  When it was clear that there was no saving our original cornice, he offered up more than one suitable way forward. We decide to let his crew re-create the original piece from stone. The work they did left us with a beautiful and artistic facade the functions well in collecting rain water from the roof. The crew was respectful, clean and on time. They went above and beyond all of our expectations in touching up every minor detail so that the whole front of the house was left looking brand new. We could not be happier. Our home looks better than we could have imagined. I recommend High Tech Construction with no hesitation.

Basement Remodel FAQs, answered by experts

It is generally more affordable to finish a basement than an attic, though it ultimately depends on how you plan to use the space. The average cost to finish a basement ranges from $7 to $23 per square foot, while attic renovation costs $30 to $60 per square foot. However, a simple attic conversion to a storage space will cost significantly less.

Adding an extension or addition to your home costs more than a loft conversion in all but the rarest cases where the home's structural integrity is lacking. Because a home addition requires a new foundation section or significant structural upgrades to handle a cantilevered portion, the cost compared to almost any loft conversion is significantly greater for the same square footage.

When considering finishing your basement, take into account a few pros and cons:

Pros

  • Can increase the value of your home

  • Separate space from the rest of the house 

  • Customize and personalize the basement to suit your needs and style

  • Increase the amount of living space in your home

Cons

  • May not regain enough value to cover the cost of finishing

  • Lack of natural light if it’s below ground level

  • Moisture or flooding can cause costly damage

  • Installing plumbing and electrical can be messy and costly

It is common for a contractor to ask for a down payment before starting a project, especially for jobs that require purchasing materials and equipment or hiring a crew. The deposit amount can range from 10% to 50% of the total job cost. While a request for up to 50% is not unusual, a contractor should not ask for more than that, and you should never pay for a project in full before the work has begun. To protect yourself, always discuss payment terms before starting and have a written contract that outlines the project timeline and expectations. Additionally, be sure to hire reputable contractors and check their licensing and insurance before the project begins.

Although it’s not required, air ventilation in a finished basement can help improve the air quality, prevent moisture and mold issues, keep musty odors away, and also maintain the air quality throughout the rest of your home. Proper ventilation will help maintain the value of your investment in finishing your basement. Try basement ventilation methods like installing vents or a dehumidifier for best results.
