Power Washing Done Right

When it comes to giving your home’s exterior a fresh, clean look, few things are as satisfying as a good power wash. Over time, siding, decks, patios, and walkways collect layers of dirt, mildew, pollen, and grime—especially after a long New England winter and a wet spring. Power washing can bring surfaces back to life, but it’s not as simple as pointing and spraying. In fact, using the wrong pressure or technique can cause real damage.

So before you rent a machine or hire someone to tackle the job, here’s what you need to know to do it safely and effectively.

What Exactly Is Power Washing?

Power washing, sometimes called pressure washing, involves using a high-pressure stream of water to clean outdoor surfaces. Some machines use hot water (true “power washers”), while others use cold. Either way, the goal is the same: remove built-up dirt, mold, algae, and stains.

It’s commonly used on vinyl siding, wood decks, fences, concrete walkways, and driveways. Done properly, it can restore surfaces to like-new condition. But when done poorly, it can strip paint, dent siding, damage wood, or even force water behind your walls, causing moisture problems you won’t notice until later.

Why Technique Matters

The biggest mistake homeowners make with power washing is using too much pressure or holding the nozzle too close to the surface. While it might feel like you’re getting a deep clean, what you’re really doing is wearing away layers of your home.

Wood decks, in particular, are easy to damage. Softwoods like pine can splinter if blasted too hard. Vinyl siding can crack or become loose. Even concrete patios can show streaks or etching if the pressure is too high. Window seals, trim, and exterior caulking are all vulnerable to water intrusion if the spray angle is too aggressive.

The key to successful power washing is using the right amount of pressure and keeping a safe distance. Professionals typically start several feet away from the surface and gradually move closer, testing as they go. They also choose the correct spray tip for the job - wider angles for delicate surfaces, narrower ones for tough stains.

When It Works and When It Doesn’t

Power washing works well on most exterior materials - vinyl siding, concrete, brick, and certain types of wood. But it’s not ideal for everything. Asphalt roofing, older masonry with loose mortar, and painted surfaces that aren’t in great condition can be easily damaged. It’s also important to avoid spraying near electrical outlets, light fixtures, or windows.

Some surfaces benefit from using a cleaning solution before washing. Mildew and algae, common in shady areas or near trees, may require a cleaner designed for siding or decks. These help break down organic growth so that the power washer can rinse it away gently.

Know When to Call in a Pro

If your home is two stories tall, has delicate finishes, or hasn’t been cleaned in years, hiring a professional might be the safer option. A reputable company will know how to get the job done without harming your home’s exterior or landscaping. They’ll also have the right equipment for harder-to-reach areas.

Power washing can be a great way to refresh your home’s curb appeal, but it’s not a job to take lightly. With the right tools and a little know-how, you can do it yourself safely. And when in doubt, a professional can help protect your investment.

Ventilation 101: How to Keep Your Attic from Turning Into a Sauna

Most homeowners don’t think about their attic unless something goes wrong. But during the hot, humid summer months in Connecticut, poor attic ventilation can cause a lot of problems. Some you’ll feel in your cooling bills, and others you might not notice until it’s too late.

Here’s why proper attic ventilation matters and how to know if your home needs an upgrade.

Why Your Attic Needs to Breathe

Your attic should be the same temperature as the air outside. That might sound surprising, but it’s true. In the summer, without proper airflow, your attic can easily reach 130°F or higher. That heat doesn’t just stay in the attic - it radiates down into your living space, forcing your air conditioner to work harder and driving up energy costs.

Hot, stagnant air can also cause your roofing materials to age prematurely. Shingles can blister, underlayment can warp, and moisture can build up, leading to mold, mildew, and even wood rot.

Good ventilation helps control both heat and moisture, keeping your attic and roof in better shape, and your home more energy-efficient.

The Basics of a Ventilation System

A well-ventilated attic has two things: intake and exhaust. These work together to create a continuous flow of air.

• Intake vents (usually located in the soffits under your roof overhang) pull fresh air into the attic.

• Exhaust vents (at the roof ridge, gables, or high up on the roof slope) allow hot, humid air to escape.

This system relies on the natural movement of air—cool air in, hot air out.

Common Ventilation Types

• Ridge vents: Run along the peak of your roof and are often paired with soffit vents. They’re effective and barely noticeable from the street.
  Soffit vents: Located under your eaves, they bring in cool outside air.

• Gable vents: Installed on the walls of the attic, often used in older homes.

• Powered attic fans: Use electricity to actively pull hot air out. These can be helpful but aren’t always necessary if passive ventilation is working properly.

Signs of Poor Attic Ventilation

• Your upstairs rooms are always hotter than the rest of the house.

• You notice high energy bills in the summer.

• Your roof shingles are curling or deteriorating faster than expected.

• There’s mold or a musty smell in the attic.

• You see frost or condensation in the attic during winter (yes, ventilation matters year-round).

Here in Connecticut, we deal with humid summers and cold winters, which means both heat and moisture are issues. That makes proper attic ventilation even more important. It’s not just about comfort, it’s about protecting your roof, improving air quality, and saving on long-term energy costs.

If you’re unsure whether your attic is properly ventilated, a quick inspection by a professional can help. It’s one of those home systems that’s easy to overlook, until it’s not.

What’s New in Deck Design This Summer

Summer in Connecticut is a great time to enjoy your outdoor space and for many homeowners, that means spending time on the deck. Whether you already have one or are thinking about building or upgrading, today’s deck designs offer more options than ever before. Here are some of the most popular trends we’re seeing this year and what you should consider if you’re planning a project.

1. Low-Maintenance Composite Decking

One of the biggest shifts in recent years is the move from traditional wood to composite decking. Composite boards are made from a mix of recycled plastic and wood fibers, and they’re designed to look like natural wood without all the upkeep. They won’t splinter, rot, or fade as quickly, and they don’t require staining or sealing every year. That makes them a great choice for homeowners who want to enjoy their deck without a lot of maintenance. The downside? They tend to be pretty pricey.

2. Natural Wood Still Has a Place

While composite decking is growing in popularity, many homeowners still prefer the look and feel of real wood. Cedar, pressure-treated pine, and even hardwoods like ipe are still solid choices. Just be aware that wood decks will need more regular maintenance, especially with our New England weather, which can be hard on exposed wood surfaces.

3. Built-In Features for More Functionality

Decks are no longer just platforms with railings. More homeowners are adding built-in benches, planters, and even lighting to make the space more functional and enjoyable. In Connecticut, where the weather can change quickly, adding a pergola or covered section can provide shade and shelter during light rain or strong sun.

4. Railing Options That Improve the View

Traditional wood railings are giving way to more modern options like cable railings, aluminum, or even glass panels. These choices help open up the space and improve your view of the backyard or nearby woods without compromising safety.

5. Planning for Storms and Drainage

With frequent summer rainstorms and occasional severe weather, it’s important to think about how your deck will handle water. Proper slope, drainage systems, and weather-resistant materials can help protect your investment and extend the life of your deck.

Things to Consider Before Starting a Deck Project

• Budget: Composite decking is more expensive up front but requires less maintenance. Wood is cheaper to install but will need more ongoing care.

• Location: If your home is near the shoreline or exposed to high humidity, look for materials that resist moisture and salt air.

• Permits: Connecticut towns have specific building codes for decks. Be sure to check local regulations and get the proper permits before starting.

A new or upgraded deck can add both value and enjoyment to your home. Whether you’re looking for a quiet place to relax or an outdoor space to entertain family and friends, today’s decking options make it easier than ever to create something that works for your lifestyle.
