Repair or replace? We'll tell you straight.

A leaking skylight might just need new flashing. A rotted corner board might point to a bigger problem behind it. Here's how we decide, and we'll walk you through it on your own home.

A repair usually makes sense when

  • A skylight leak traces back to failed flashing, not the unit itself
  • Damage is limited to one trim board, shutter or section of soffit
  • A window or door just needs new caulking or weatherstripping
  • The wood and framing underneath are solid

It's usually time to replace when

  • A skylight is fogged, cracked or as old as the roof around it
  • Windows are drafty, fogged between panes or hard to open
  • Trim, soffit or fascia is soft and rotted in more than one spot
  • You're repainting trim or shutters every few years just to keep up
  • Animals or insects are getting in through damaged soffit or vents

They did an absolutely amazing job replacing our siding, gutters and adding an awning on our back porch. As a Home Inspector I am in houses every day and often see things that are missed or poor craftsmanship, but Jenack's work is absolutely amazing and their attention to detail is second to none. The owner Jack and his crew were a pleasure to work with and really gave us personalized attention and made recommendations to help us along the way. I highly recommend this company and will recommend them to all my clients in the future.

Jack's company replaced our gutters and they turned out great! They were very communicative throughout the process and even came out early on day it was going to rain to get the install done before it started raining!

Jack did an excellent job on my home. He walked me through the entire process, explained everything clearly, and made sure I understood what was being done. He followed up afterward to check if I had any concerns, which really showed how much he cares about his customers. His professionalism and communication made the whole experience smooth and stress‑free. Highly recommend his services.

Jenack was great. Did not jump through hoops like others in providing a quote. One visit, one quote. The best quote I received! One call to schedule the work. Delivery of project materials on a Friday. Completed work Monday and Tuesday with full clean up. I called about a very minor gap in caulking and the owner came out the next day and fixed it. A great company to work with.

One of the best contractor/client experiences I’ve had. Work was performed on time according to agreed upon start and finish. All damage items brought to site replaced that same day and installed per contract. Highly recommended contractor from an architect with 30 years in the business.

Jack is a really great guy! Very personable, considerate, honest. Seems to know what he's doing, too. He's been very good in inspecting, evaluating, and repairing the flat roof of a Baltimore row house we bought last year. When it comes time to replace it, I think we know who we'll call.

I can’t say enough about how Jack and his crew hung in there with me to make sure everything right. With years of architecture behind me sometimes you know too much and Jack was there with open arms to make sure I had things done to my liking. In the end, our home looks so much better. I can’t thank him enough for being so great even through the little things… like the dumpster truck leaving a rut… Jack just showed up with topsoil and seed and took care of it all right away!

I contracted with Jack Scrof/Jenack Construction this spring to replace my back door and storm door. Communication was excellent, unlike some experiences I've had with other contractors. He and his crew were professional, friendly, worked hard and smart, and did a super job replacing the door. I appreciate the outstanding customer service Jenack provided and would 100% recommend them for your work.

Exterior service questions

Have a question that isn't here? Call us or send it with the form below.

Why is my skylight leaking?

Most skylight leaks come from failed flashing, not the skylight itself. We'll find the source and tell you whether it needs new flashing or a new unit.

Should I replace my skylights when I get a new roof?

Usually, yes. Skylights and roofs tend to wear out together, and replacing them at the same time means new flashing and no need to disturb the new roof later.

Is PVC trim worth the cost?

It costs more than wood upfront, but it won't rot or need painting, so it often costs less over time.

What is metal trim capping?

It's aluminum custom-bent to wrap your window and door trim, protecting the wood underneath and eliminating painting.

Can you fix animals getting into my soffit or attic?

We replace damaged soffit, fascia and vents to close up the openings. For animals already inside, you'll want a wildlife removal service first.

Can you replace just one window or door?

Typically when one window fails, the other windows are not far behind. The seals around the glass and frame wear out overtime. For that reason, we recommend replacing several windows at once. Even if you aren't ready to replace your full house, replacing one side - like the side that gets the most direct sun - is the best approach.
