Amazing what a new front door can do for your home.

Swapped out the old dated entry for this modern expresso and black door system and it completely changed the front of the home.

If your front entrance needs an upgrade, now’s the time. Free estimates available.

What a difference new windows and a door can make!!

What originally needed a little TLC is now clean, bright, sealed properly, and completely refreshed. This isn’t just a replacement, it’s a full transformation inside and out.

If your windows or doors are drafty, damaged, or outdated, you’re probably not seeing your home at its full potential. Done right, this is one of the biggest upgrades you can make.

Spots are filling up fast, reach out to me soon to get your free estimate or call me to get on the schedule!

BEFORE TO AFTER DONE RIGHT!!
This was a 2 part transformation.
We replaced a dated, leaky half round transom with a clean, modern rectangle design, which instantly sharpened the look.
Then we upgraded the front door, thats when it really came to life!
The results?
A beautiful, elegant entry way that completely changed the curb appeal.
This one definitely turned some heads.
If your entry feels outdated, THIS is your sign.
Spring and summer installs are filling up fast.
Don't wait, call now to book your free estimate!

Yes we also do siding, eavestroughs, and custom capping!!

This project was finished some time last year, I just never got around to posting it. The owners of this home were "blown away", their words not mine, but we did smash it outta the park. It was a tedious job, with many curve balls, but could not be happier with the end results. Had to sneak a few evening pictures at the end to show off their new pot lights. It’s all about the details!

If you’re looking at having your home B-E-A-Utified give me a call/text at 519-991-2866 or send me a DM.

Spring is right around the corner, and a lot of homeowners are starting to think about the projects they want to tackle this year.

New windows and doors can completely change the look and feel of your home, more natural light, better airflow, and a fresh updated appearance from the outside.

If your windows are hard to open, fogged up, or your front door has seen better days, this might be the year to upgrade.

At Deroy Construction, I handle the supply and installation so the process is simple and done right.

If you’ve been thinking about replacing a window or door this year, now is a great time to get an estimate and get ahead of the spring rush.

Another basement window upgrade completed.

Double sliding windows installed on this job.

Three old windows out, three new ones in. Everything cleaned up and finished with new interior casing for a clean look inside, along with beautiful custom capping on the exterior.

The homeowner was thrilled with the results and really liked the flexibility of being able to open these however they want. These will also help with airflow and energy efficiency compared to the old basement windows.

If you’re thinking about updating your windows, feel free to reach out.

Free estimates available.

Another beautiful finish. You could not see the backyard before we installed these new windows. With a view like that windows were essential. Not my usual supplier, but what the customer wants, the customer gets.

Thank you, thank you, thank you. I did it, we did it, what a great outcome! I'm so happy I dont know how to describe it. My heart is so full right now. There were over 104,000 push uppers, we completed over 84,000,000 push-ups combine and raised over $3,000,000 for this amazing cause. To be a part of something this big has me feeling grateful beyond words. This challenge proved what’s possible when we show up, stay consistent, and move together. I’m walking away stronger, more connected, and more inspired than ever.
With love,
Ken
Stronger together.
Keep tuned in to find out what's next!
