What you need to know about siding your home

Our properties put on siding like a wintertime coat, bundled up in cedar-check plaids or vinyl stripes to endure the weather. And when that overcoat is searching tattered — whether or not your home is clad in 100-yr-aged painted pine shingles, 60-yr-old asbestos-cement tiles, 50-12 months-previous aluminum, or 30-12 months-previous vinyl — you may well entertain the strategy of changing it with new siding.

It is a tough decision, because in contrast to a roof — which, when it fails, needs to be replaced pronto — “siding is additional of a want than a want,’’ explained John MacDonald, general supervisor of REI Roofing & Siding in Holbrook. And as desires go, it is not a affordable a single: The common expense to switch 1,250 sq. ft of vinyl siding in the Boston place is $24,626, in accordance to Remodeling Magazine’s 2022 Charge vs. Worth Report.

But number of other home improvements have these a dramatic, instant impact on suppress enchantment. Homeowners can expect to recoup about 80 per cent of a vinyl siding project’s price tag at resale, in accordance to the exact same report, making it one particular of the most financially fulfilling improvements.

It is also 1 of the most confounding, simply because there are so quite a few alternatives. And as the very first impact your home tends to make on guests, siding is a large-stakes decision — a single that, with any luck, will very last for a number of many years. So here’s what to know in advance of deciding on a spiffy new appear for your home.

Wooden siding

In the modern-day market, household siding alternatives can be simplified into two principal types, mentioned Joseph Danz, president of Boston Exterior Remodeling in West Roxbury. “There’s synthetic siding, and there’s genuine wood siding.’’ Properties have worn many species of wooden above the years, but the two major kinds of wooden siding are red and white cedar, both equally of which are normally rot-resistant due to the fragrant tannic acids observed in their heartwood.

Red cedar, which grows out West, is a taller tree with a denser grain, so it can be made use of for larger shingles, clapboards (those people prolonged, horizontal strips), and shakes (similar to shingles, but with a thicker and rougher cut that gives them more texture and heft). Japanese white cedar, grown in areas like Nova Scotia and Maine, is a scaled-down species applied primarily for shingles — like the kinds you see on Nantucket.

Cedar is the most sustainable siding materials out there, explained Phil Kaplan, principal at Kaplan Thompson Architects in Portland, Maine, and co-host of the Inexperienced Architect’s Lounge podcast — at minimum, if it was harvested responsibly. He suggests inquiring for wooden qualified by the Forest Stewardship Council. “More people must truly start off on the lookout at FSC lumber,’’ he reported. “The price tag quality is not as fantastic as it utilised to be.’’ Due to the fact Jap white cedar is grown nearby, it has the the very least embodied carbon — that is, the emissions resulting from its harvest, output, and transport to the work website — of any siding.

Cedar can come pre-stained or pre-treated with oils to lengthen its lifespan (if staining or painting, make sure to coat all sides of a shingle or clapboard prior to installation for optimum longevity). But even remaining untreated, cedar is durable. “Cedar shingles will previous for 20, 25 years on the wall if they are untreated,’’ MacDonald explained. “If they are handled, you will get even longer out of them.’’ Pink cedar tends to darken as it ages, though white cedar normally fades to grey.

The major drawback? Cedar siding is expensive, specially at the minute. Among COVID shutdowns and provide chain problems, MacDonald said it is gotten pricier or even not possible to procure the product essential to side an whole home in cedar. “Lumber yards have had a truly tricky time obtaining that at a superior price tag, so it is not something you can genuinely quote these days,’’ he explained. “Because a lumberyard will only provide you — if they even have it — a constrained total, typically not ample to do a full home.’’

There are a handful of newer and area of interest wood siding alternatives, too, like some that rely on natural treatment plans to increase their lifespan. Acetylated wood, for instance, is addressed with acetic anhydride (a a great deal stronger relative of vinegar), and torrefied wooden is mainly baked at pretty large temperatures to strip it of its electrical power, creating it significantly less vulnerable to pests and mold. “These properly wood-dependent products and solutions are a great deal extra long lasting they don’t rot,’’ Kaplan said.

Artificial siding

When it arrives to rot resistance, while, vinyl and other minimal-maintenance, non-pure supplies have gained favor with homebuilders and owners. In 2020, 72 p.c of the new households created in New England ended up sided with vinyl, in accordance to census study facts, in contrast with 16 p.c clad in the runner-up, wooden.

And even though conventional vinyl siding — the ubiquitous double-rowed panels of 4-inch clapboards, seams and all — is the most reasonably priced siding solution, “there are minor tips of the trade to truly make vinyl appear not like vinyl,’’ Danz claimed, these types of as having treatment to set on authentic window trims. “This is not the days where Sears applied to wander around the community and promote you slender vinyl siding that only came in a few colours.’’

If a home owner can find the money for the enhance, Danz likes to use a product or service termed Grayne: a cedar-appear artificial siding made from PVC. “It seems to be like person cedar shingles, but it will come in a panel,’’ he explained. “The other great point about it is it has 2 percent squander and a Class A fireplace rating — which is unheard of.’’

As a vinyl up grade, MacDonald is a enthusiast of CertainTeed Cedar Impressions, which are designed of PVC and appear in a assortment of textures, measurements, and hues. Nonetheless, the intricate installation will increase labor costs and squander. “It’s a really specific cut and nailing pattern, so alternatively of the 10 per cent squander issue you have with wooden siding or fiber cement or vinyl clapboard, it’s more like a 20 percent waste variable,’’ he claimed, specifically when mounted on an old Victorian with nooks and crannies or various home windows. “The labor is double the cost [of standard vinyl siding], and then to acquire the substance is virtually 4 instances the value,’’ he explained.

Other composite siding choices include TruExterior, produced from polymer and fly ash (a byproduct of coal combustion) Everlast, which is about 80 p.c PVC-based mostly resin combined with inorganic supplies (these as crushed stone or fly ash) and very long-lasting acrylic colorant and SmartSide, produced from strands of wood treated with zinc borate and certain with wax and a non-PVC resin.

From a sensible standpoint, a different rationale Danz likes Grayne is that it’s effortless to take out if a home owner would like to place on a deck or addition later on. “Everlast is a stunning merchandise, but it has this locking mechanism in which they stack on major of each other, so you cannot get off a panel mid-wall,’’ he mentioned.

A further composite content, fiber-cement siding, has developed hugely well known in the earlier two many years. It usually has cellulose, cement, and possibly sand or fly ash. That tends to make the products long lasting if installed appropriately, but also major and hard for contractors to do the job with. Fiber cement isn’t vulnerable to insects, fireplace, or rot — and although it requires significantly less upkeep than wooden, it does occasionally get in touch with for a new coat of paint, which it retains nicely.

Some fiber-cement boards include silica dust, nevertheless, which can be unsafe to installers when they slash it to dimension. And homeowners have had combined benefits with the merchandise CertainTeed paid out above $100 million to settle a class action lawsuit alleging its fiber-cement siding warped and cracked prematurely.

“We never contact fiber-cement siding,’’ MacDonald mentioned. “It draws a great deal of dust, the solution breaks effortlessly — so at REI we just decide on not to use that item.’’

“In center The usa, it seems to be okay, but in New England, it just gets eaten alive,’’ Danz agreed. “I’ve taken off additional cement board than I have at any time put on.’’

“Not all fiber cement is the same,’’ countered Andrew Bella, director of profits/Northeast location for James Hardie, probably the best recognized producer of fiber-cement goods in New England. “Hardie fiber-cement merchandise have been exclusively engineered for local weather to stand up to harsh New England weather, resisting problems from h2o, pests, rot, substantial winds, temperature extremes, hail, and even fire.’’

It is what’s beneath that counts

For all the notice paid out to siding, it is the things underneath that truly does the challenging do the job of safeguarding your home from the elements. “All siding is sacrificial to some extent,’’ Kaplan mentioned. “The siding, in and of alone, is not the factor that keeps the water out.’’

That occupation falls on a temperature barrier, this sort of as a Tyvec or Typar home wrap, or a peel-and-stick membrane such as Vycor or BlueSkin, that’s used over the sheathing (the boards or plywood that comprise your exterior walls). “[The siding] effectively guards the drinking water barrier from immediate exposure to the sunlight and rain in buy to preserve that water barrier in fantastic shape,’’ Kaplan claimed.

That is 1 purpose Danz normally strips off aged siding as a substitute of installing new substance instantly around the outdated. “You’re only as superior as what you are nailing something to when you do individuals go-overs,’’ Danz said, and the previous siding could be hiding rotten sheathing or other difficulties. “We only have one particular formula, exactly where we strip every thing down, repair the rot, increase Vycor.’’ (Danz prefers Vycor to BlueSkin for the reason that it is extra clear, so he can see what’s powering the membrane. But the two solutions are a phase up from standard residence wrap, furnishing air sealing in addition to water resistance.)

In cedar applications, in individual, there’s just one final critical undergarment: a rain display screen. No matter whether it’s a mesh layer that sits behind the shingles, or a series of skinny strapping boards that create an air channel driving the clapboards, it’s crucial to allow the siding to drain and dry out.

“It fundamentally generates a hole between the siding and the drinking water-resistant barrier that makes it possible for airflow to get behind there, so you do not have siding pushing immediately from sheathing, where it has a tendency to rot if it will get wet,’’ Kaplan said. And the openings at the top rated and bottom ought to have true screens on them, to keep bugs out.

Time to decorate

Everyone who’s bought a new coat understands it’s a good event to choose up a matching hat or scarf, if there’s home in the spending budget. In the same way, there are other home jobs that dovetail perfectly with new siding.

If you’re searching to update windows, for example, without the need of resorting to substitute windows (which increase a frame in just the current frame, dishonest you out of treasured daylight), a siding task is the opportune time to do it. It’s also a great time to get insulation blown into your partitions, something most Massachusetts citizens can get carried out at a steep low cost by means of Mass Preserve. “The very best insulation you can have is often the things that goes in your partitions,’’ Danz stated.

After all, in New England, it doesn’t seriously matter how awesome your new coat looks if it does not continue to keep you warm and dry on a chilly January evening.
